Why does the chloroplast utilize a cyclic electron pathway as well as the noncyclic electron pathway?
A)The noncyclic electron pathway does not provide enough NADPH for the cell.
B)The noncyclic electron pathway does not provide enough oxygen for the cell.
C)The Calvin cycle utilizes more NADPH than ATP and the cyclic electron pathway produces NADPH.
D)The Calvin cycle utilizes more ATP than NADPH and the cyclic electron pathway produces ATP.
E)The cyclic electron pathway only runs when oxygen is limiting.

Question

Quizplus · Accepted Answer

The Calvin cycle requires more ATP than NADPH, and the cyclic electron pathway helps produce additional ATP without producing NADPH.
