The stent energy in the form of ADP is regenerated by mitochondria into__________?

Correct answer: C. ATP

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

Explanation

Mitochondria regenerate ATP from ADP by adding inorganic phosphate during oxidative phosphorylation: ADP + phosphate forms ATP. ATP is the immediately usable energy-carrying molecule, whereas AMP has fewer phosphate groups and is not the normal product of this regeneration. The likely mistake is choosing ADP because it appears in the question, even though ADP is the starting molecule.
