Which of the following steps of aerobic respiration is amphibolic?

Options

  1. AGlycolysis
  2. BOxidative decarboxylation of pyruvate
  3. CTCA cycle
  4. DOxidative phosphorylation

Correct answer

C. TCA cycle

Step-by-step solution

Respiration is part of the metabolic process where the nutrients are converted into useful energy for regular cell activities. It is in two mode depending on presence or absence of oxygen. Aerobic respiration is the one where oxygen is involved and anaerobic respiration is the process where oxygen is absent. TCA cycle or Kreb's cycle of respiration process is considered amphibolic because it has both anabolic and catabolic processes. In this pathway, there is catabolism of the glycolysis end product - pyruvate to p
