D
Cytoplasm
Verified step by step guidance
1
Understand the process of photosynthesis, which consists of two main stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Recognize that light-dependent reactions require light energy to produce ATP and NADPH, which are used in the Calvin cycle.
Identify the location within the chloroplast where light-dependent reactions occur. Chloroplasts have a double membrane structure with internal thylakoid membranes.
Recall that thylakoid membranes contain chlorophyll and other pigments that capture light energy, making them the site of light-dependent reactions.
Conclude that the light-dependent reactions of photosynthesis take place in the thylakoid membranes of the chloroplast.
