D) They are not related.

Question

Quizplus · Accepted Answer

The products of light-dependent reactions (ATP and NADPH) are used in light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose. Therefore, the light-dependent and light-independent reactions of photosynthesis are related and interdependent.
