Question

Q16.Which of the following is an important difference between light-dependent and light independent reactions of photosynthesis?

1.The light-dependent reactions occur only during the day; the light-independent reactions occur only during the night.
2.The light-dependent reactions occur in the cytoplasm; the light-independent reactions occur in chloroplasts.
3.The light-dependent reactions utilize CO2 and H2O; the light-independent reactions produce CO2 and H2O.
4.The light-dependent reactions produce ATP and NADPH; the light-independent utilize ATP and NADPH

Answer 1

Answer:

please mark as brainliest and please follow me

Explanation:

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

so the correct answer is (a)
