In respiratory electron transport chain, the first ATP is formed from ADP and inorganic phosphate, utilizing the free energy obtained by oxidation of :
Correct answer: A. NADH
- A. NADH
- B. FADH
- C. Coenzyme Q
- D. Cytochrome C
Explanation
It is first step of respiratory electron transport chain in which NADH is oxidized by coenzyme Q. This oxidation yields enough free energy to permit the synthesis of a molecule of ATP from ADP from ADP and inorganic phosphate.
