Kreb’s Cycle
|
Detailed explanation-1: -Also known as the citric acid cycle, the Krebs cycle or TCA cycle is a chain of reactions occurring in the mitochondria, through which almost all living cells produce energy in aerobic respiration. It uses oxygen and gives out water and carbon dioxide as products. Here, ADP is converted into ATP.
Detailed explanation-2: -Step 3. Isocitrate is converted into -ketoglutarate in a reaction catalyzed by isocitrate dehydrogenase. An NAD+ molecule is reduced to NADH + H+ in this reaction, and a carbon dioxide molecule is released as a product. Step 4.
Detailed explanation-3: -Cellular respiration converts ingested nutrients in the form of glucose (C6H12O6) and oxygen to energy in the form of adenosine triphosphate (ATP). CO2 is produced as a byproduct of this reaction.
