KREBS CYCLE MADE EASY.
The Krebs cycle (named after Hans Krebs) is a part of cellular respiration. Its other names are the citric acid cycle, and the tricarboxylic acid cycle (TCA cycle). The Krebs cycle comes after the link reaction and provides the hydrogen and electrons needed for the electron transport chain.
LINKS:

Glucose is the molecule that is ultimately metabolized by living things to derive energy, in the form of adenosine triphosphate, or ATP. Glucose can be stored in the body in numerous forms; glycogen is little more than a long chain of glucose molecules that is stored in muscle and liver cells, while dietary carbohydrates, proteins and fats have components that can be metabolized to glucose as well. When a molecule of glucose enters a cell, it is broken down in the cytoplasm into pyruvate.

What happens next depends on whether the pyruvate enters the aerobic respiration path (the usual result) or the lactate fermentation path (used in bouts of high-intensity exercise or oxygen deprivation) before it ultimately allows for ATP production and the release of carbon dioxide (CO2) and water (H2O) as by-products.

The Krebs cycle – also called the citric acid cycle or the tricarboxylic acid (TCA) cycle – is the first step in the aerobic pathway, and it operates to continually synthesize enough of a substance called oxaloacetate to keep the cycle going, although, as you'll see, this is not really the cycle's "mission." The Krebs cycle supplies other benefits as well. Because it includes some eight reactions (and, correspondingly, nine enzymes) involving nine distinct molecules, it is helpful to develop tools to keep the important points of the cycle straight in your mind.
As noted previously, the fate of pyruvate depends on the metabolic demands and the environment of the organism in question. In prokaryotes, glycolysis plus fermentation provides almost all of the single cell's energy needs, although some of these organisms have evolved electron transport chains that allow them to make use of oxygen to liberate ATP from metabolites (products) of glycolysis. In prokaryotes as well as in all eukaryotes but yeast, if there is no oxygen available or if the cell's energy needs cannot be fully met through aerobic respiration, pyruvate is converted to lactic acid via fermentation under the influence of the enzyme lactate dehydrogenase, or LDH.

We are truly so fortunate to have accessibility to helpful videos such as this one. Never thought I'd be able to understand the Krebs Cycle but after this, I do now!! Thank you so much!!

This video is way more understandable than the old one.
A big salute to you sir 🙏🙏.

thank god for you! you make cellular respiration not to look like a nightmare, I must have re about the concept 20 times and watched videos about it another 20 times, but I didn't understand until now. these kind of videos, specially now in the pandemic where I have to teach myself microbiology, are complete game changers! thanks, and keep them coming!

I was always afraid to approach cellular respiration but you made me fall in love with it by your presentations and explanations. Thank you! Looking forward to more videos.

The "Nobel Youtube Prize" is in order for such a fantastic video.
Thank you for taking the time and effort to make such an outstanding resource.

As a Biology teacher I know that Many teachers dread teaching Krebs cycle, but this is absolutely superb and my learners respond well to this video.

The best KREBS Cycle explanation I've seen. Still beyond me to actually understand this complex metabolic process/principle, but helps me understand the basic Krebs Cycle and how it manages our metabolism.

Now I need to understand how to manage my diet to maximize my my Krebs Cycle(s) and perhaps reduce the terrible thing that hangs over my belt. Thanks!!

I am a bio teacher. I watched your previous video also. I clicked that why you have uploaded again. 😂

You are too good sir. Thanks.

I'm persuing msc in chemistry. So in 2nd sem, there is a additional Book life science. & I am a non-medical student. So bio, I don't understand it at all. You explain every steps very clearly. This video is really very helpful to me. Thanks

I ABSOLUTELY LOVE your channel! You are an amazing educator!
Thank you for taking complicated processes and simplifying them without losing any of essential aspects of the concepts you cover!

This one is a fascinating channel. Everything minutely explained so is easy to analyse and imbibe. I'm in earnest, thank you so much and keep doing things like this!
