Conversion of NAD+ into NADH requires:
Correct answer: A. 2 electrons, 1 proton
- A. 2 electrons, 1 proton
- B. 2 Electrons 2 protons
- C. 1 Electron 2 protons
- D. 1 Electron 1 proton
Explanation
The conversion of NAD+ into NADH is a reduction process that requires the addition of 2 electrons and 1 proton. This results in the formation of NADH from NAD+. The correct option (A) reflects this requirement. Options B, C, and D are incorrect because they do not represent the accurate stoichiometry needed for the reduction of NAD+ to NADH.

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.
