this is why the 0:11 cell performs cellular respiration it's 0:15 trying to make this because ATP is the 0:17 energy molecule used by the cell you'll 0:20 often hear ATP as an analogy compared to 0:23 money or the currency of a cell because 0:26 you know we spend money on goods and 0:27 services and the cell will spend ATP to 0:32 perform you know these these reactions 0:35 and many others that I did not list but 0:38 here's the triphosphate part notice how 0:41 there are three phosphates and they're 0:42 in the bonds of these three phosphates 0:45 particularly between the second and 0:47 third phosphate is energy and in the 0:51 hydrolysis of ATP if you've forgotten 0:53 that hydro means water and lysis means 0:56 to break down so in the breakdown of ATP 1:00 ATP with water will yield adp a single 1:06 phosphate and energy and it's this 1:08 energy that will power the cell and so 1:12 in this very simplified diagram of an 1:15 ATP molecule here comes water and my 1:18 scissors represent the actions of an 1:20 enzyme and that third phosphate tends to 1:24 be broken off and in that energy is 1:27 released and it's this energy that will 1:29 often drive the cellular processes that 1:31 you see listed in the notes so how is 1:35 this molecule of ATP created well ATP 1:40 gets created through cellular 1:42 respiration cells need ATP to power 1:45 their chemical reactions and most ATP 1:48 gets produced by the powerhouse of the 1:51 cell the mitochondria the powerhouse 1:53 because it produces the ATP power now 1:56 ATP is created through this process of 1:59 cellular respiration which we're going 2:01 to go through in the rest of this video 2:03 and what happens is a molecule of 2:06 glucose that we get from our food is 2:08 gonna be broken down to make a whole 2:10 bunch of molecules of ATP 2:12 that's what half 2:14 during the the process of cellular 2:16 respiration glycolysis the Krebs cycle 2:19 the electron transport chain these are 2:21 all breaking down molecules of glucose 2:24 from our food to produce ATP so let's 2:27 move into glycolysis okay starting with 2:31 glycolysis the location takes place in 2:35 the cytoplasm of a cell and what happens 2:38 is that blue hexagon ring labeled 2:43 glucose glucose is going to be broken 2:45 down by molecules of ATP a molecule 2:48 called nad in various enzymes now for 2:51 simplicity I've only drawn the six 2:54 carbons of glucose in my diagram but 2:58 glucose you can see also has 12 3:00 hydrogen's and six oxygens so what 3:04 happens is two molecules of ATP plus and 3:08 plus enzymes are going to begin to break 3:10 down glucose then this might seem a 3:12 little counterproductive using ATP to 3:15 make ATP but keep in mind the goal is to 3:19 make a lot of ATP so if you have to 3:20 spend a little bit of ATP to make a lot 3:23 of ATP it's worth it 3:25 so a molecule of ATP plus the scissors 3:28 representing an enzyme will begin to 3:31 break down glucose into this 3:34 intermediate molecule here so next 3:39 another molecule of ATP and a different 3:42 enzyme will be broken down and the 3:45 energy from ATP will break that 3:48 intermediate down into two molecules 3:50 labeled P gal or phosphoglyceraldehyde 3:53 now P gal itself this is another 3:56 intermediate it will be broken down 3:58 further in a moment 4:00 so next enzymes which are in the 4:03 cytoplasm will add another phosphate 4:06 unto each of the P gals so here's an 4:08 enzyme the scissors adding a phosphate 4:11 to the P gal on the left and and the 4:13 phosphate being added to the P gal on 4:15 the right and by doing this this 4:18 converts the P gal into another 4:20 intermediate molecule 4:22 so next couple molecules called NADH are 4:27 going to be created and will enter the 4:28 mitochondria well they begin as 4:30 molecules call of nad and nad is in 4:34 abbreviation for nicotinamide adenine 4:36 dinucleotide and what happens of course 4:39 there's enzymes involved nad with the 4:42 help of an enzyme will strip off the 4:44 hydrogen to create NADH NADH can be 4:48 looked at as a hydrogen carrier carries 4:50 the hydrogen over to the mitochondria 4:52 the same thing happens with the other 4:54 nad an enzyme will help to strip off a 4:57 hydrogen and NADH will carry that 5:00 hydrogen over to the mitochondria these 5:02 are going to be very very important when 5:05 we get to the electron transport chain 5:08 so now that we're near the end of 5:11 glycolysis let's talk about how four 5:13 molecules of ATP are created 5:15 you see those four yellow circles with 5:18 the P those each represent a phosphate 5:21 group and what happens is here is four 5:24 molecules of ATP and ADP along with the 5:28 help of an enzyme will strip off one of 5:31 those phosphates to create a molecule of 5:33 ATP now this happens three more times an 5:37 ADP with the help of an enzyme will 5:40 strip off one of those phosphates to 5:42 make ATP adp strips off a phosphate to 5:47 make ATP and ADP again strips off a 5:51 phosphate with the help of enzymes to 5:53 make ATP and what we're left with what 5:57 was once glucose is now these two 6:00 molecules called pyruvates and the 6:02 pyruvates are gonna be very useful in 6:04 the Krebs cycle coming up we also have a 6:07 total amount of four ATP molecules 6:10 created although sometimes you'll hear 6:12 it referred to as a net gain of two 6:14 ATP's well what do we mean by that well 6:17 four ATP's are created but two ATP's 6:20 were used to start the process of 6:22 glycolysis so when you subtract the two 6:24 at the start from the four that were 6:27 created that's what we made net gain 6:29 well what happens next 6:32 what happens next depends upon the type 6:36 of cell and the conditions that the cell 6:38 is within there's two possible pathways 6:41 and both of them are going to involve 6:43 those pyruvates those pyruvates are 6:45 going to be broken down even further the 6:47 pathway that we're gonna follow in these 6:50 notes is the aerobic pathway with oxygen 6:53 leading to the Krebs cycle and the 6:55 electron transport chain 6:57 but if oxygen is lacking if a cell is in 6:59 an anaerobic environment those pyruvates 7:02 will be used in fermentation I have a 7:05 different video if you want to learn 7:06 about fermentation but this video is 7:08 gonna follow the aerobic pathway so here 7:13 we are back at our cell glycolysis has 7:16 just completed itself and we're about to 7:18 start the krebs cycle and so the two 7:20 molecules of pyruvate will migrate into 7:23 the mitochondria so let's go into the 7:26 mitochondria and take a closer look and 7:30 when we zoom into the mitochondria so 7:34 there's the two pyruvates notice how 7:36 they're in the mitochondrial matrix the 7:39 inner inner fluid layer of the 7:42 mitochondria and so what happens is 7:45 we're gonna follow the pyruvate on the 7:46 left now the same thing happens the 7:49 pyruvate on the right but for simplicity 7:51 we're gonna just follow the one on the 7:52 left the peruvians gonna be broken down 7:55 into acetic acid in the process of doing 7:58 this NADH is gonna be created so there's 8:01 a molecule of nad when pyruvate is being 8:05 broken down nad will come and strip off 8:07 a hydrogen to make NADH notice Haussmann 8:11 carbon dioxide was created as well 8:13 that's just waste what we're left with 8:16 is acetic acid acetic acid being a 8:18 intermediate molecule what happens next 8:22 is a really large molecule that I'm 8:24 being very simplistic in just drawing it 8:27 and labeling it Co a coenzyme a really 8:31 large molecule will bond to acetic acid 8:33 well how big is coenzyme a we'll look at 8:36 the formula of acetic acid when we bond 8:38 coenzyme a we form acetyl co a look at 8:42 how large that formula is 8:44 so acetyl co a is also an intermediate 8:47 molecule it's just the next step of the 8:50 krebs cycle what happens to the acetyl 8:54 co a the third step and this is where 8:56 this the krebs cycle also gets its name 8:59 of the citric acid cycle acetyl co a is 9:03 going to be converted and broken down 9:04 into citric acid that happens when a 9:09 four carbon molecule from the previous 9:11 krebs cycle bonds to the acetyl co a and 9:16 i have it flashing for a reason I hope 9:19 you all understand why it's flashing 9:20 when we get to the end I wanted to do 9:23 something for you to member out to 9:25 remember this four carbon molecule from 9:28 the previous krebs cycle so an enzyme 9:31 will bond that four carbon molecule to 9:35 the acetyl co a and the coenzyme a 9:38 breaks away and what you're left with is 9:41 citric acid citric acid being a six 9:45 carbon molecule okay so the six carbon 9:50 citric acid will be broken down into a 9:53 five carbon molecule and in the process 9:56 of doing this NADH is created so here's 9:59 a molecule of nad nad along with an 10:02 enzyme will help to break down the 10:05 citric acid notice how NADH was created 10:08 also some carbon dioxide waste was 10:11 generated this is why citric acid went 10:14 from a six carbon to a five carbon 10:16 molecule so what about this five carbon 10:21 molecule this five carbon molecule is 10:23 again an intermediate it's gonna be 10:25 broken down into a four carbon molecule 10:27 and in the break down a couple things 10:29 happen 10:30 number one another molecule of NADH is 10:33 created so there's nad with the help of 10:35 an enzyme nad will strip off a hydrogen 10:38 but that's not the only thing that 10:40 happens a molecule of ATP will be 10:43 created because in the matrix of the 10:46 mitochondria there are various solutes 10:48 and molecules dissolved within the 10:52 matrix and here's a molecule of adp and 10:55 a phosphate and 10:57 bring these molecules together and in 10:59 the breakdown of this five carbon 11:02 molecule into a four carbon molecule the 11:04 ATP is bonded together and also in the 11:10 act of doing this carbon dioxide waste 11:13 is created so that's how it goes from a 11:15 five carbon to a four carbon molecule 11:18 now this four carbon molecule is again 11:21 an intermediate enzymes will rearrange 11:25 the four carbon molecule into another 11:28 four carbon molecule and in the process 11:32 of doing this a molecule of NADH is 11:36 created that means we have to have nad 11:38 come along and strip off a hydrogen and 11:41 then another molecule very similar to 11:44 nad called 11:46 F ad is gonna come on in and strip off 11:48 not one but two hydrogen's forming fadh2 11:53 now all of these NADH is in this fadh2 11:57 they have a role to play we just haven't 11:59 seen it yet their role is coming up in a 12:02 few moments well what happens with this 12:06 four carbon molecule that's just been 12:08 rearranged notice how it's flashing now 12:10 that's because this is the same flashing 12:13 four carbon molecule we saw earlier 12:15 remember the Krebs cycle is a cycle so I 12:17 wanted to do something for you to 12:19 realize when the krebs cycle was 12:21 beginning its next turn and what happens 12:25 with this four carbon molecule it will 12:27 bond with acetyl co a that really big 12:31 molecule we saw earlier so enzymes will 12:33 bind it together the coenzyme a breaks 12:36 away and what we're left with is the six 12:39 carbon molecule known as citric acid and 12:41 the process repeats itself well when we 12:45 look at what's created an overview of 12:47 the Krebs cycle this always frustrated 12:49 me because I always thought that you 12:51 know cellular respiration is purpose is 12:53 to make a lot of ATP and only two 12:55 molecules of ATP were created one 12:58 molecule of ATP from the pyruvate on the 13:00 left one molecule of ATP from the 13:02 pyruvate on the right but the big prize 13:05 of the krebs cycle is not the two 13:07 molecules of ATP it's all the nad 13:10 and fadh2 that was created those are 13:14 really important in the electron 13:16 transport chain so let's look at that 13:18 next so as we move on into the electron 13:22 transport chain what we're gonna do is 13:24 we're gonna zoom in to the membrane of 13:26 the matrix and when we zoom on in here 13:30 here we are so now that we've zoomed in 13:34 we can see embedded in the inner 13:36 mitochondrial membrane are some great 13:40 herbs and cylinders these are symbolic 13:42 of the protein complexes that are 13:45 embedded inside this membrane here and 13:48 these are gonna help to kind of drive 13:51 the electron transport chain 13:53 now we're gonna see why all the nadh and 13:55 fadh2 is created well here's a molecule 13:58 of NADH enzymes of course are going to 14:01 help break this down and notice how a 14:03 couple of electrons are now embedded in 14:06 the inner mitochondrial membrane and one 14:09 of the hydrogen ions has positioned 14:11 itself at one of those protein tubes 14:14 well this happens repeatedly another 14:17 NADH is broken down couple more 14:19 electrons embed in the inner 14:22 mitochondrial membrane another hydrogen 14:24 is positioned itself at one of the 14:26 protein tubes and here's an fadh2 that's 14:29 broken down and what we're seeing is the 14:32 beginning of the electron transport 14:34 chain those electrons are going to start 14:36 a chain reaction which we've called the 14:39 electron transport chain well what 14:43 happens with with these electrons this 14:46 is why it's called the electron 14:47 transport chain these electrons are 14:49 going to start a chain reaction of 14:51 events where those hydrogen's are going 14:53 to be transported out of the matrix and 14:56 so the electrons as they transfer from 15:01 protein channel to protein channel by 15:03 protein channel as they transfer from 15:06 the protein channels they provide the 15:09 energy to pull these hydrogens out of 15:13 the matrix and this will set up the next 15:17 step of the electron transport chain 15:21 so once all the hydrogens have been 15:23 pulled out of the matriot out of the 15:26 matrix they have accumulated in a very 15:28 large amount now and this is going to 15:30 lead to really rapid diffusion through 15:33 the molecule labeled ATP synthase and so 15:38 those hydrogen ions are going to 15:40 activate this enzyme this molecule 15:42 called ATP synthase and notice how ATP 15:45 synthase has an adp and a P attached to 15:50 it they just need the ATP synthase just 15:52 needs something to bond the phosphate 15:55 with the ADP and that's the job of the 16:00 hydrogen ion so what the hydrogen does 16:03 is it loads itself into ATP synthase 16:06 simple diffusion from a high 16:08 concentration to a low and as the 16:10 hydrogen diffuses through the mechanical 16:13 forces bring together the adp and the P 16:16 to create ATP and this happens 16:20 repeatedly over and over and over so 16:23 here's another adp and another phosphate 16:25 here's another hydrogen and as the 16:28 hydrogen diffuses through ATP is created 16:31 and this happens repeatedly over and 16:34 over and over up to 34 times well as we 16:40 wind down notice how there are some 16:44 hydrogens and electrons that are now 16:46 regather incide the matrix there has to 16:49 be a way to clean these up in order to 16:52 keep the process moving and this is 16:55 where the water is formed if you look at 16:57 the chemical formula of cellular 16:59 respiration one of the one of the 17:02 products that's formed as water 17:05 well oxygen from the air that we breathe 17:08 well bond with two of the hydrogen's and 17:12 two of the electrons to form a molecule 17:14 of water this is where we get the water 17:18 in the chemical reaction of of cellular 17:21 respiration it comes from the end of the 17:24 electron transport chain 17:27 so if you're in my class we'll talk 17:30 about this essay in more detail well as 17:35 I wrap this up I

I can now visualize the entire process in my head, rather than memorizing random numbers!! I don't understand why it isn't always taught this way. Thank you from the bottom of my heart. One question: what software did you use to animate this? I think if I could make more of my own visualizations in the future, I'd be able to teach myself more complex concepts in quite the same way. 5 Reply @azurebluet3045 2 years ago I wish MY teacher explained in detail--and carefully, knowing we have minimal knowledge on the topic.

Thank you! 3 Reply @mike5774 4 years ago It wold be fantastic if u ordered steps of respiration for us u asked at the end of video. Visualization videos are much understandable and attaches obsession into the subject, after all we are not more than a obsession and a belief. Textbooks are fantastic in describing how events and history is connected in any discipline but to provoke our mankind's thinking into microworld we need visualization videos. We are interested in forklore and stupidity is becos we cannot perceive microworld through our senses. Seeing is an necessary element to create curiosity into science.
