Compare and contrast fermentation as it occurs in your muscle cells and in yeast cells.

Hello, everybody. Today we've been talking about a very interesting topic. That is the production off Dina seen Tribe us today the 80 p molecules. The's ADP molecules are present in our bodies on our immensely important before I begin with its code, a process of production. Have a leg you ought to know and understand. Then what are these molecules? You can think that a debate molecules are like chemical factories of the cell that store a lot of energy whenever needed. The body cells you with ease 82 molecules to release that stored energy and use it to carry out white ill activities of the body on to ensure our survival. Now the process that produces thes immensely important molecules is called cellular respiration. He's crosses, is very, very, very important and has three main steps. The first step is glad Collis is The second step is a citric acid cycle. On the third step is oxidative boss. More elation remember in step off cellular respiration is immensely important as each step produces a certain number off 80 b molecules, the first on the second step that is die Collis iss on the citric acid cycle produced at our 12 to 80 p molecules. But this last step, the oxidative phosphor relation, produces the highest number of a TV molecules in the process of cellular respiration that IHS our own 30 to 36 molecules up a DP. Now I will start by explaining What is this process off oxidative boss Correlation. What occurs throughout this process? And how are these so many 80 B molecules for use in this process? So I have drawn he simplified diagram over here. Don't worry. I know it still seems a bit complicated, but I promise it's not that difficult. Before I start to explain what happens, I would like you all to know I'm remember that this process occurs in the inner of my joke. Andrea Member Raid Let me highlight that for you. Yes. So this process occurs in the inner my to con brio memory. The blue boxes on the blue circles drawn in this diagram represent protein molecules that have been embedded in the inner mighty conjure memories. The process begins when the surgeon electron carrier molecules such as in a D. H on F a d h to travel to words the electron transport chain? No. What are these electron carrier molecules? The carrier molecules are those molecules that have gained certain number off electrons from the processes that occur prior to oxidative possible relation on and turned reviews themselves. Now what is electron transporting? The other thing that is very important in this process. The electron transport chain is the is a consists off certain number off protein molecules that are embedded in the inner my to conjure, remembering on help in the transportacion off electrons from vie protein to the next. Let me holla Dad for you. So this is the electron transport chain. The hell's an immense importance in this process. Off oxidative boss relations. Let's continue the process. So what's the electron carrier molecules travel towards the inner mitochondrial members are towards the electron transport change that is embedded in the inner mitochondrial memory. They lose some off their energy because they lose some of their electrons. So I would like to draw an electron that I'm representing it as e negative to show the negative charge of the electrons. So the ask, uh as electronics carriers lose some of the electrons to the electron transport chain, they become oxidized as represented in the over here. On over here, you can see how the N a T H was converted to any D plus, as did lost some of its electrons to the literal transport ship and how the FDD age do converted to F A D H plus when it lost some of its electrons to the in a conference for change. Now, as electrons enter the electron transport chain, they are carried from one protein present and electron transport J to the next on to the next. Now this movement off electrons from one protein to the next is very, very important as it leads to other processes being carried out. For example, the oxygen present the oxygen present in the near the inner Michael Kahn remembering combines with these electrons to form water. You can see the process of a here, how the electrons combine with the oxygen to produce water, and this is how the byproduct off cellular respiration, that is water is good used. The second important thing iss the occurs due to the transfer of electrons in the throughout the electric transport chain is the transportacion off hydrogen Iam's Let Me Holla Doctor, all you in another color over here so you can see in hydrogen ion. So the transport ensure of electrons to Adelaide from transport chain and during provides energy for the Transportacion off hydrogen islands from the my took 100 omi tricks into the in dura membrane space across the concentration Grady in. Now this process leads to the formation off higher hydrogen ion concentration in the inter membrane space on lower hydrogen ion concentration. The mitochondrial matrix. Since there is a concentration difference between off hydrogen, I let me repeat that. I'm sorry. Since there is a difference in the conservation of hydrogen islands in the inter member in space and in the light of Condra matrix, these hydrogen aisles returned back from the intra membrane space into the mitochondrial matrix down the concentration radiant. Now, this movement of hydrogen islands from the in German brand space into the mitochondrial matrix causes a protein embedded in the inner mitochondrial membrane. Or, you can say 1/3 by light substance embedded in the inner mitochondrial membrane to rule. Take now, as this turbine rotates, the rotation causes the production off ADP molecules. This process is called Kimio communal assists. I hope implement pronouncing that correctly. So this process is how the hard the 80 B molecules come into formation. This process you presents how the A TV molecules are formed in oxidative false relation. On That's it. Thank you.

Most of the ATP in respiration comes from what like dialysis citric acid cycle, the electron transport system lactic production or anaerobic pathways. Okay, first of all, aerobic respiration is more efficient than anaerobic. Okay, so it's not an aerobic pathways and it's not going to be lacks a production because that's only in the anaerobic pathway. The anaerobic pathway. Anaerobic an Arabic gives to ATP glucose that is inefficient. So let's look at the Arabic. Well I've said anaerobic gives to and that's because it gets all from the black hole Asus like analysis. Michel assis Gives You two ATP so the lacks a production is just to get rid of waste products. Big like analysis is what gives you the people anaerobic. It only gives you two in Arabic. So it's not stop producing much about. Then we have the citric acid cycle. This gives you another suit. So citric acid cycle Gives you another 2 80. So clearly we can see that most of it is coming from the electron transcription. This is C. So now you might be wondering how much do you get? Okay, so the maximum is 34. So maximum potential by the sec Is 34 ATP but realistically we don't hit this you won't be getting 34 ATP from every every run of the electron transport chain. And that's because of the cost of moving the pyro bait into the mitochondria and also that the protons across the membrane. The membrane is slightly leaky. So you don't get every single proton pump out resorting in ATP production some of it the expectorant services for maximum potential, but it's still far more efficient than all the others.

So whenever if you're talking about anaerobic or aerobic reactions, uh the key here is oxygen. If it's aerobic, it requires oxygen. If it's anaerobic, it doesn't need oxygen or prefers not to react with oxygen at all. In this case we were asked that which of these reactions is aerobic, which is part of our uh cellular respiration. So let's start with which is not aerobic or anaerobic. And the one I could think of in my head is black analysis. We could completely eliminate black analysis because it does not require oxygen. It is the first step. And even cells that are anaerobic, I don't need it uh oxygen to produce because they do with black policies or fermentation and uh the next step and all of it occurs in the mitochondria. Not two but three of these steps are given to us the conversion of peru to a single ceo a our citric acid cycle or are electron transport chain. Um even though they all occur in the mitochondria, not all of them are aerobic reaction here. It is a redox reaction, but there is not direct oxygen involved. Here is just nz informing our any deep age over here. And so we can eliminate this option. Even though uh citric acid cycle is directly connected with our electron transport chain as it delivers our electron carriers, it does not stop when there is a reduction in oxygen, it can be inhibited but it is not directly inhibited. There is no involvement of oxygen. There is involvement of water which does get recycled and therefore there is no direct involvement in citric acid cycle. But in electron transport chain, after forming our chemical gradient, after having our electron transporters deliver our electrons through the gradient at the end. There is this very crucial moment may be the most crucial when it comes to aerobic respiration is that Through 80% tastes, we have a proton go down the gradient, turning the ATP synthesis to produce ATP. But this only occurs when our proton is being accepted by our final electron. Except er which is our oxygen and half of that oxygen with two of our protons reform R. H. D. O. This might ring a bell because this is exactly the reverse of our photosynthesis reaction where the water was split and the oxygen was snatched from our I mean the electrons were snatched from our oxygen atoms but here are final electron except er is oxygen, especially in our solar respiration and that's why an electron transport chain. It's absolutely absolutely crucial to have oxygen. Otherwise we will be stuck in like analysis and that is it for this video. And thanks for watching.

Tp production in, uh, in the cell in which stages over the metabolic process produced how much it up. So, uh, we start the process with, like, Allah assists right in this one. We have a energy input, actually, to start this whole reactions, we have to a t p n, and we get some glucose converted to colle assists. And that's gonna also give us to a teepee out. Okay, then the great khal Asus. Ah, couple of things happen. We have, um so we have ah, the n a t h production, and we also have the power of it that comes out of it. Now the Perovic heads towards our crab cycle, and the Krebs cycle is gonna produce a measly, uh to a t p. Right. There's any D h. Um, it's gonna pull in some of the products of the Krebs cycle, you know? So there's the Krebs cycle goes, it's gonna pull in two and a th other two. It's gonna then pull in six and a D. H. And then it's just gonna keep taking stuff from this cycle. And then we're gonna get to F A. D. H two. Well, this leads us to our, uh, fancy electron transport chain. So it's called the e transport, and this chain produces but 32. 80 p. Eso. The whole process creates 36. 80 p. But 32 of that 36 comes from the electron transport chain. So the correct answer here is going to be see most. 80 p comes from the electron transport chain.
