Web24 Nov 2024 · The light reaction is a major component of photosynthesis. It is in charge of converting light and energy into chemical energy in the first place. Because of this … WebSunlight is used in the light reaction of photosynthesis where the plants make the energy molecules like ATP and NADPH. These energy molecules are later used for the preparation of sugar molecules in dark reactions. Hence the process of photosynthesis can be divided into light dependent and light independent reactions.
