Question

The importance of Krebs cycle is in the production of

• A. Acetyl Co-A
• B. Water
• C. ATP
• D. ADP

Answer 1

The correct option is C ATP

Krebs cycle is a step in aerobic respiration, where ATP molecules are generated in large number. This cycle consumes acetate and water, reduces $NA{D}^{+}$ to NADH, and produces carbon dioxide as a waste product. The NADH generated by the cycle is fed into the oxidative phosphorylation pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of ATP.
