Question

If the concentration of hydrogen ions (H+) outside of 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

B

Step-by-step explanation:

Answer 2

The concentration gradient is what makes the intramembrane proteins work. If there is no gradient, or in other words, the concentration is the same outside and inside the thylakoids, the ATP synthase would not be able to produce any ATP. So, the correct answer is: "B. The chloroplasts would be unable to generate ATP."
