Multiple Choice
Researchers developing herbicidal chemical agents tested one, compound Q, on the ability of chloroplasts isolated from spinach leaves to carry out three stages of photosynthesis under illumination.The results are shown in the table below.
The table indicates the levels of activity in these photosynthesis stages.The number of "+" signs indicates the relative level of activity, while "0" indicates no activity.Which statement is consistent with these results?
A) Compound Q binds to one of the electron carrier proteins in photosystem I and inhibits its ability to accept electrons.
B) Compound Q inhibits NADP+ reductase, the enzyme that catalyzes the transfer of electrons in the formation of NADPH.
C) Compound Q induces the light reactions and light-independent reactions to lose their dependency on light.
D) Compound Q reverses the sequence of the light reactions and light-independent reactions.
E) Compound Q allows protons to leak through the thylakoid membrane, disrupting the ability of the chloroplast to synthesize ATP required by the Calvin cycle.
