Answer:
Capture light energy and convert this light energy into chemical energy
Explanation:
During the light reaction of photosynthesis, both the photosystems photosystem I and and photosystem II get activated and excited electrons from these photosystems received by various receptors and they travel downhill according to the gradient. As a result of this downhill movement of electrons, NADPH and ATP are formed. These are further used in light independent reactions to produce sugar molecules which act as an energy source for the plants.
Thus the primary function of the light reaction is to capture light energy and convert this light energy into chemical energy.
Answer:
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
i hope this helps you.
