Question

Select the set of correct statements regarding ETS in aerobic respiration.
A. \(F_{1}\) catalyses the synthesis of ATP from ADP.
B. Protons are channeled from outer chamber of mitochondria into inner chamber by \(F_{0}\) part of oxysome.
C. Cytochrome C acts as mobile electron carrier transferring electrons from Complex V and IV.
D. Cytochrome C is a small, calcium containing protein tightly associated with inner membrane.
E. Cytochrome C acts as mobile electron carrier transferring electrons from complex III to IV.
Select the correct option

• A. A, B and C only
• B. A, C and D only
• C. C and D only
• D. A, B and E only

Hint:

Cytochrome c carries electrons from complex III to complex IV.

Answer 1

The Correct Option is D

Step 1: Check A and B
A is true: the \(\text{F}_1\) head of the oxysome makes ATP from ADP and Pi. B is true: the \(\text{F}_0\) part is a channel through which protons flow from the outer chamber to the inner chamber.

Step 2: Check C, D, E
C is false because complex V is ATP synthase. D is false: cytochrome c is a small iron haem protein loosely held on the outer face of the inner membrane. E is true: cytochrome c carries electrons from complex III to IV.

Step 3: Conclusion
The correct statements are A, B and E only.

Final Answer:
The correct statements are A, B and E. \[ \boxed{\text{(D) }\text{A, B and E only}} \]
