Question

During the light reactions part of photosynthesis, chlorophyll in the chloroplast captures energy from the sun. What is this light energy used for?

Answer 1

In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
