Malate is oxidized by _ to oxaloacetate in Krebs's Cycle.
Correct answer: C. NAD
- A. ATP
- B. NADP
- C. NAD
- D. FAD
Explanation
NAD (nicotinamide adenine dinucleotide) is involved in the oxidation of malate to oxaloacetate in the Krebs's Cycle. NAD acts as a coenzyme that accepts hydrogen atoms (H+) and electrons (e-) during the redox reactions in cellular respiration, including the Krebs's Cycle.

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.
