Question

hb unit 2.1 cell energy and photosynthesis quiz 2025 (connected m where do the light - dependent reactions take place? in the stroma within the thylakoid membranes in the mitochondria only in chlorophyll molecules

Explanation:

The light - dependent reactions of photosynthesis occur within the thylakoid membranes. Chlorophyll and other pigments embedded in the thylakoid membranes absorb light energy, which is used to generate ATP and NADPH. The stroma is where the light - independent reactions (Calvin cycle) occur. Mitochondria are involved in cellular respiration, not photosynthesis. While chlorophyll is important for capturing light, the reactions don't occur only in chlorophyll molecules but in the thylakoid membrane structure.

Answer:

B. within the thylakoid membranes
