What's the importance of krebs's cycle?
- A
Production of amino acids
- B
Production of vitamins
- C
Production of ATP molecules through oxidative phosphorylation
- D
Production of pyruvic acid
During steps 3, 4, and 8 of Krebs' cycle, 3 molecules of NADH + H+ are produced by oxidative decarboxylation of isocitrate, alpha-ketoglutarate, and malate, respectively. These NADH + H+ molecules are converted into ATP molecules by oxidative phosphorylation. Hence this option is correct.
Krebs' cycle is concerned with complete oxidation of acetyl group of acetyl-CoA. There is no production of amino acids in Krebs' cycle.
Krebs cycle is concerned with complete oxidation of acetyl group of acetyl-CoA. There is no production of vitamins in the Krebs' cycle.
