Which source of energy powers the light-independent reactions of photosynthesis?  
A)light
B)ATP and NADPH
C)photosystem 2
D)glucose
E)NADP+

Quizplus · Accepted Answer

The light-independent reactions, also known as the Calvin cycle, require energy in the form of ATP and NADPH, which are generated during the light-dependent reactions of photosynthesis. Therefore, choice B is the correct answer. Light (choice A), photosystem 2 (choice C), glucose (choice D), and NADP+ (choice E) are not sources of energy for the light-independent reactions.
