The most accurate statement regarding the first stage of photosynthesis is:
Radiant energy is converted into chemical energy, and this is a light-dependent stage.
In the light-dependent reactions of photosynthesis, which occur in the thylakoid membranes of chloroplasts, light energy is captured and used to convert ADP and NADP+ into the energy carriers ATP and NADPH. The formation of sugar molecules like glucose occurs in the subsequent light-independent stage (Calvin cycle).
