D

Verified step by step guidance
1
Understand that photosynthesis consists of two main stages: the light-dependent reactions and the Calvin cycle (light-independent reactions).
Recognize that the light-dependent reactions occur in the thylakoid membranes of the chloroplasts and require light energy to proceed.
Know that during the light-dependent reactions, light energy is captured by chlorophyll and other pigments, which excites electrons and initiates a series of reactions.
Learn that the excited electrons move through the electron transport chain, leading to the production of ATP and NADPH. This process is known as photophosphorylation.
Conclude that ATP is produced during the light-dependent reactions of photosynthesis, which provide the energy required for the subsequent Calvin cycle to synthesize glucose.
