Question

If the concentration of hydrogen ions (H+) outside the thylakoids were equal to the concentration of H+ inside the thylakoids, how would it affect the chloroplasts?
A. The chloroplasts would release excess O2

B. The chloroplasts would be unable to generate ATP

C. The chloroplasts would make more glucose molecules

D. The chloroplasts would make more NADPH than usual

Answer 1

The answer is :B. The chloroplasts would be unable to generate ATP

When there is a concentration gradient, there is an unequal distribution of ions across the thylakoids. As long as this gradient exists due to the protons(H+) moving in the thylakoid lumen, the ATPase can produce ATP.

Answer 2

The correct answer is option b
