That's the goal of these cy- these, these steps.
N
39:21Nirosha MuruganGUEST
Eventually, they end up in the electron transport chain, where that electron kind of moves through it to get to its eventual home of oxygen.
N
39:29Nirosha MuruganGUEST
Um, that oxygen is what's gonna help create this reactive oxygen species.
N
39:35Nirosha MuruganGUEST
So I'm not sure if within the TCA there's gonna be much light generation.

... that gets through down to the axon and, and onto the next cell.
N
70:27Nirosha MuruganGUEST
Um, and if we take that same analogy and kind of apply it to mitochondria, with that electron flow in the electron transport chain, where's the pattern? Is that the pattern that we should be looking at? I'm not sure if anyone's looked into this, and I think those are the types of things that people kind of should reframe in terms of dynamics.

So we're not just measuring the number of ATP that may get made.
Cellular Respiration Part 3: The Electron Transport Chain and Oxidative Phosphorylation
D
0:47Dave FarinaHOST
As it turns out, neither process generates much of an energy payoff, but the NADH and FADH2 that were generated in the citric acid cycle move on to oxidative phosphorylation, which generates by far the most ATP out of these pathways.
D
1:04Dave FarinaHOST
This pathway utilizes an electron transport chain, which is a series of mitochondrial membrane proteins that sit in the inner membrane of the mitochondrion, and we refer to these as protein complexes one through four.
D
1:19Dave FarinaHOST
These proteins bear a variety of prosthetic groups, which are non-protein components that give the protein its functionality, including flavin mononucleotides and cytochromes.
D
1:31Dave FarinaHOST
There is also one compound in the electron transport chain that is not a protein, and that's ubiquinone, a small hydrophobic molecule that is mobile within the membrane, and it is also known as coenzyme Q, or CoQ.
D
1:45Dave FarinaHOST
Once NADH feeds electrons into the first component of complex one, these proteins facilitate a series of redox reactions, shuttling the electrons downhill from one component to another, with each structure down the chain having a higher affinity for electrons than the last.
D
2:04Dave FarinaHOST
This process does not generate ATP directly, but a byproduct of this series of electron transfers is the generation of a proton gradient across the membrane.
D
3:43Dave FarinaHOST
So in summary, your body uses a variety of metabolic pathways.
D
3:47Dave FarinaHOST
Glycolysis, the most ancient, produces two ATPs per glucose, but it also results in pyruvate, which can enter the citric acid cycle.
Your Body Stops Making This Antioxidant After 30
C
24:16Catharine ArnstonGUEST
But what I ask people is, well, where is the inflammation coming from? Because 99% of chronic diseases are due to inflammation in the mitochondria.
C
24:26Catharine ArnstonGUEST
But where's the inflammation coming from? And so the inflammation, through my research, I have found is coming from something called the electron transport chain, which is actually where the actual cellular energy is created within the mitochondria.
C
24:40Catharine ArnstonGUEST
People are... becoming more familiar with mitochondria.
C
24:43Catharine ArnstonGUEST
But what is it in the mitochondria that's making all that ATP? And what is it that's causing all that inflammation? And what makes all that energy is this thing called the electron transport chain.
C
24:55Catharine ArnstonGUEST
And the thing that causes all the inflammation is when the electron transport chain gets damaged.
C
25:00Catharine ArnstonGUEST
And the nutrients found mostly in spirulina, but also chlorella, restore and protect the electron transport chain.
C
25:07Catharine ArnstonGUEST
And so now with the electron transport chain is working, you're not going to have as much inflammation.
C
25:13Catharine ArnstonGUEST
You're not going to need NAD.
C10E8: Oxidative Phosphorylation
K
0:19KellyHOST
Welcome again.
K
0:21KellyHOST
This episode is all about the electron transport chain, which creates energy through oxidative phosphorylation.
K
0:29KellyHOST
This pathway requires two areas with different hydrogen concentrations, so we need a membrane to separate them.
K
0:36KellyHOST
This membrane is mitochondria in eukaryotic cells, but in bacterial cells that don't have organelles, it happens in the cell membrane, and the second space being between the cell membrane and cell wall.
K
0:51KellyHOST
The electron transport chain is the final stage of aerobic respiration and where most ATP is produced.
K
0:58KellyHOST
By this point, earlier pathways like glycolysis and the Krebs cycle have filled those electron buses, our NAD and FAD molecules, and they deliver electrons to a series of proteins embedded in the membrane.
K
1:12KellyHOST
This is known as the electron transport chain.
K
1:16KellyHOST
As electrons move from one protein to the next, they lose energy step by step.
C10E7: Glycolysis & The Krebs Cycle
K
6:36KellyHOST
Each glucose produces two spins of the cycle, so two more ATP are made, eight NAD buses are filled, two FAD buses are filled, and our glucose turns to ash a little at a time in the form of CO2.
K
6:50KellyHOST
NAD and FAD carriers then move to the electron transport chain, where electrons pass through proteins, releasing energy to pump hydrogen ions and create a gradient.
K
7:02KellyHOST
ATP synthase uses this gradient to produce ATP in oxidative phosphorylation.
K
7:09KellyHOST
Oxygen is the final electron acceptor forming water.
K
7:12KellyHOST
Now, these two steps of metabolism, Krebs cycle and electron transport chain, are coupled.
K
7:17KellyHOST
The first part gathers the electrons, and the second part offloads them and captures the energy.
K
7:23KellyHOST
Up to 38 ATP can be produced per glucose in aerobic respiration.
K
7:59KellyHOST
In aerobic respiration, the Krebs cycle comes next and generates NAD and FAD buses while releasing CO2.
Testing AI as a Learning Partner

8:16Renee JordanHOST
Think of sunlight as an energy boost that powers up an electron.
R
8:21Renee JordanHOST
Those energized electrons enter an electron transport chain, or ETC, a series of proteins embedded in the thylakoid membrane that transfer electrons from one molecule to another.
R
8:37Renee JordanHOST
Here's where the chemistry gets interesting.
R
8:39Renee JordanHOST
Water molecules, H2O, are split.
Episode 153. How Infrared Light Actually Affects Your Mitochondria - Hypothesis
R
3:02Roger SeheultHOST
Folks, what we're saying here is that the infrared light that comes from the sun and its particular area, band, if you will, is able to penetrate deeply into our body, is able to affect the mitochondria in ways that change the arrangements of where these electrons are actually being transferred so that they could be transferred more easily in some cases, and sometimes less easily.
R
3:26Roger SeheultHOST
So in other words, it modulates the electron transfer in the mitochondria and the electron transport chain.
R
3:32Roger SeheultHOST
And because of that, with certain exposure to infrared light, we can get actual improvement in metabolism, which is very important, especially when it comes to aging, survival, and other medical issues.
R
3:45Roger SeheultHOST
Let's dive in to exactly what we're talking about.
5 MINS LATER
R
9:16Roger SeheultHOST
And they go through, in terms of pyruvate, fatty acids, amino acids, they go into the citric acid cycle where they go around and around and they produce these high energy electrons called NADH, FADH2, and also GTP.
R
9:31Roger SeheultHOST
It is from these high energy electrons that will eventually make ATP, which is over here.
R
9:36Roger SeheultHOST
How do we do that though? We have to go to something called the electron transport chain.
R
9:41Roger SeheultHOST
And this is where we're going to be spending the rest of the talk because this is where the rate limiting step is.

22:04Daniel J. GuerraHOST
So, indeed, NAD is an essential coenzyme primarily regarded for its use in redox, reduction oxidation reactions.
D
22:13Daniel J. GuerraHOST
And of course, those reactions are intimately linked via the ETC, OXFOS, to mitochondrial ATP synthesis.
S

Now, while NAD is not permeable
D
22:31Daniel J. GuerraHOST
by itself, NAM, on the other hand, nicotinamide mononucleotide, direct product, will readily cross the plasma membrane.
SS-31, Methylene Blue & MOTS-c: The Correct Order to Run Them
B
16:52Barry NapierHOST
It has a unique mechanism of action.
B
16:54Barry NapierHOST
Again, another compound, does a lot of cool stuff, has a lot of great benefit, but specifically has some awesome benefit in terms of mitochondrial function and helping move things along that electron transport chain.
A
17:05Angila JaeggliHOST
Yeah, so methylene blue is an antioxidant, and when it comes to the mitochondria, it actually provides the fuel or electrons for the energy to basically be processed down the line of that electron transport chain.
A
17:22Angila JaeggliHOST
And so why that's important is that if there are areas that are damaged or missing, the methylene blue can help bypass those damaged areas.
A
17:32Angila JaeggliHOST
And so works in conjunction with that SS31.
Authentic Biochemistry Podcast Adiposity-Associated Inflammation Dyslipidaemia 20September26 XXVI Dr. Daniel J Guerra.
D
34:34Daniel J. GuerraHOST
So then you end up with a dysfunctional complex four.
D
34:39Daniel J. GuerraHOST
And that dysfunctional complex four that remember is the terminal oxidase, cyclops oxidase, the electron transport chain is the last complex of the ETC.
D
34:51Daniel J. GuerraHOST
And that, by the way, that gene, That's encoded by the nucleus.
D
34:56Daniel J. GuerraHOST
So the protein has to be trapped in the mitochondria for this to work.
D
35:38Daniel J. GuerraHOST
They directly regulate those microRNAs ATP synthesis because they are targeting and therefore diminishing the expression of many of the other nuclear genes that nevertheless play a role in mitochondrial electron transport activity.
D
35:57Daniel J. GuerraHOST
Now, why is that such a significant thing? Well, if you didn't know it, the mitochondria has its own genome.
D
36:03Daniel J. GuerraHOST
So yes, most of the mitochondrial genes are used in the mitochondrial activity, including ETC and oxidative phosphorylation and transporters and whatnot.
D
36:14Daniel J. GuerraHOST
But many of the other proteins still necessary for the mitochondrial function are now found in the nucleus.
