Question

What are the products of light-dependent reactions? Why are they important in light-independent reactions?

Answer 1

ATP is a product of light-dependent reactions.

NADPH is a product of light-dependent reactions.

ATP and NADPH are used in light-independent reactions to make glucose and other carbohydrates.

Answer 2

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.
