Question

4 multiple choice 1 point where do the light - dependent reactions of photosynthesis take place? in the thylakoid membrane in the stroma in the cristae in the cytoplasm

Explanation:

Photosynthesis has two main stages: light - dependent reactions and light - independent reactions (Calvin cycle). The light - dependent reactions require light and occur in the thylakoid membrane. Chlorophyll and other pigments in the thylakoid membrane absorb light energy. This energy is used to split water (photolysis) and produce ATP (through chemiosmosis) and NADPH. The stroma is where the light - independent reactions (Calvin cycle) occur. Cristae are structures in mitochondria (related to cellular respiration, not photosynthesis). The cytoplasm is a general cell compartment and not the specific site for light - dependent reactions of photosynthesis.

Answer:

A. In the thylakoid membrane
