Biology

The light-dependent reactions are named as such because they rely on light energy. Pigments like chlorophyll absorb photons of light and convert it into chemical energy during the light-dependent reactions of photosynthesis, leading to the production of ATP and NADPH. Without light energy, the light-dependent reactions cannot occur.

The other options are incorrect:

Option A: The light-dependent reactions occur in the thylakoid membranes of the chloroplasts. The stroma is the site of the lig...
