The spent energy in the form of ADP is regenerated by mitochondria into which of the following form?

Correct answer: B. ATP

  • A. AMP
  • B. ATP
  • C. ADP
  • D. All of these options are correct

Explanation

Mitochondria are membrane-bound organelles, and those membranes function for the purpose of mitochondria, which is essential to produce energy. That energy is produced by having chemicals within the cell go through pathways. And the process of that conversion produces energy in the form of ATP because phosphate is a high-energy bond and provides energy for other reactions within the cell. So the mitochondria's purpose is to produce that energy. Hence, option C is incorrect.

About Bioenergetics

Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
