During chemiosmotic synthesis at ATP in photosynthesis

A the protons accumulate in the intermembrane space of chloroplast
B the proton gradient is not required
C the protons accumulate in the intermembrane space of mitochondrion
D the protons accumulate within lumen of the thylakoids

Verified Solution

Answer & Solution

Correct Answer

(D) the protons accumulate within lumen of the thylakoids

Step-by-step Solution

Detailed explanation

(D) the protons accumulate within lumen of the thylakoids,
ATP synthesis is linked to development of a proton gradient across thylakoid membrane. There is one difference though, here the proton accumulation is towards the inside of the membrane, i.e., in the lumen.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
