What is the electron transport chain? Explain in detail. Cellular Respiration: Cellular respiration is made up of four basic steps: Glycolysis. The pyruvate dehydrogenase complex (pyruvate oxidation). The citric acid cycle (Krebs cycle). Oxidative Phosphorylation. ...
and fatty acids. Each glucose molecule produces 2 molecules of pyruvate and 2 molecules of ATP in the cytoplasm, and finally, in mitochondria, the citric acid cycle (also known as the Krebs cycle) produces up to 32 molecules of ATP. Fatty acid oxidation entering the citric acid cycle can ...
Also called the tricarboxylic acid (TCA) cycle or the Krebs cycle, this series of anaerobic reactions, like the preparatory reaction, takes place in the mitochondrial matrix. Here, the two acetyl-CoA molecules from the preparatory reaction combine with a number of phosphate and nucleotide components...
Although the Krebs cycle nets 2 molecules of ATP, this is an insignificant amount compared to the amount we’ll generate later on in the process. The last stage we’ll talk about today is oxidative phosphorylation, which is a process the electron transport chain (ETC) uses to generate ATP....

In the Krebs cycle, oxygen is used to convert carbohydrates, fats, and proteins into carbon dioxide and water, generating energy in the process. In a separate process, pyruvate can be converted into a compound called oxaloacetate, which is also a necessary component of the Krebs cycle. ...
The Urea Cycle Why Is Urea Important? A Final Word Urea is a relatively non-toxic organic compound that aids in the breakdown of nitrogen-containing compounds and potentially toxic metabolic byproducts. Urea is produced in the liver through the Urea Cycle, which occurs in both themitochondriaand...
Without the required electron carriers, the Krebs cycle grinds to a halt. If the cell had no backup plan to regenerate NAD+, glycolysis would also cease, and the cell would rapidly die. The method of removing the electron from NADH in the absence of oxygen is to pass the electron to ...
