Answer #1

1. Answer: Option C is correct
Explanation:
Complex-II participates in the electron transport chain.
But, it does not pump protons from the mitochondrial matrix to the perimitochondrial space.
So, it is not directly involved in establishing the proton gradient required for ATP synthesis.

2. Answer: Option A is correct
Explanation:
The number of c-subunits in ATP synthase of mammalian mitochondria = 8

3. Answer: Option E is correct
Explanation:
Hill coefficient > 1: Positive cooperative binding
= Sigmoidal kinetics

4. Answer: Option F is correct
Explanation:
All the given reactions occur during the TCA cycle in mammals.
