Select the set of correct statements regarding ETS in aerobic respiration. A. F₁ catalyses the synthesis of ATP from ADP. B. Protons are channeled from outer chamber of mitochondria into inner chamber by F₀ 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. Cyto

- AA, B and C only
- BA, C and D only
- CC and D only
- DA, B and E only
Correct answer
D. A, B and E only
Step-by-step solution
Statement A is correct. The F₁ headpiece of ATP synthase contains the catalytic site for the synthesis of ATP from ADP and inorganic phosphate. Statement B is correct. The F₀ part of the oxysome (ATP synthase) forms a transmembrane channel that facilitates the diffusion of protons from the intermembrane space (outer chamber) to the mitochondrial matrix (inner chamber). Statement C is incorrect. Cytochrome c transfers electrons between Complex III (Cytochrome bc₁ complex) and Complex IV (Cytochrome c oxidase), not C
