The link between Kreb's cycle and glycolysis in carbohydrate metabolism is:
Correct answer: D. Acetyl CoA
- A. Citric acid
- B. Oxaloacetate
- C. Succinate
- D. Acetyl CoA
Explanation
Acetyl CoA is the link between glycolysis and Kreb's cycle. Acetyl CoA is formed after decarboxylation of pyruvate. This acetyl CoA then enters Kreb'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.
