During photosynthesis, the Calvin cycle
A) uses ATP and NADPH to produce sugars.
B) moves electrons from Photosystem II to Photosystem I.
C) moves light-energized electrons to Photosystem II.
D) absorbs light from the light reactions.

Question

Quizplus · Accepted Answer

The Calvin cycle uses ATP and NADPH from the light reactions to produce sugars (specifically, glucose) from carbon dioxide (CO2) in the stroma of the chloroplast. This process is also known as carbon fixation. The other choices describe processes that occur during the light reactions of photosynthesis, which is separate from the Calvin cycle.
