Question

Which of the following statements on Proton gradient and ATP synthesis are correct ? A. Protons accumulate in the mitochondrial matrix.
B. PMF drives ATP synthesis.
C. ATP synthase is also called complex IV.
D. Chemiosmotic theory was proposed by Peter Mitchell.
E. ATP is synthesized during electron transfer through complexes.
Choose the correct answer from the options given below :

• A. \(B, C, D\) only
• B. \(A, B, C\) only
• C. \(B, C, D, E\) only
• D. \(C, D\) only

Hint:

Remember: \[ \text{ETC pumps protons} \rightarrow \text{PMF generated} \rightarrow \text{ATP synthase produces ATP} \]
• Complex I, III, IV \(\rightarrow\) Proton pumping
• ATP synthase \(\rightarrow\) Complex V
• Peter Mitchell proposed chemiosmotic theory

Answer 1

The Correct Option is A
