A)NADPH and ATP
B)an electrochemical gradient
C)carbohydrate molecules
D)NADPH, ATP, and an electrochemical gradient
E)NADPH, ATP, and carbohydrate molecules

Quizplus · Accepted Answer

In the light-dependent reactions of photosynthesis, light energy is captured and stored as potential energy in the form of NADPH, ATP, and an electrochemical gradient across the thylakoid membrane. The NADPH and ATP are then used in the light-independent reactions (Calvin cycle) to synthesize carbohydrates. Therefore, the correct answer is D, as it includes all three forms in which the energy is stored in the light-dependent reactions.
