प्रश्न
Why should the light-dependent reaction occur before the light-independent reaction?
Advertisements
उत्तर
During light-dependent reaction, photosynthesis pigment absorbs the light energy and convert it into chemical energy ATP and NADPH2.
During light-independent CO2 is reduced into carbohydrates with the help of ATP and NADPH2 produced during the light-dependent reaction.
