1. Why can pyruvate dehydrogenase be said to be a multienzyme complex and what is its significance in beriberi which results from a thiamine deficiency?

2. Explain in detail the chemiosmotic mechanism in oxidative phosphorylation.

3. with reference to the respiratory complexes of the electron transport chain , explain why NADH oxidation yeilds 3ATP whereas FADH2 oxidation only yeilds 2ATP?
