Which of the following is an important difference between light-dependent and light-independent reactions of photosynthesis? the light-dependent reactions occur only during the day; the light-independent reactions occur only during the night. a the light-dependent reactions occur in the cytoplasm; the light-independent reactions occur in chloroplasts. b the light-dependent reactions utilize co2 and h2o; the light-independent reactions produce co2 and h2o. c the light-dependent reactions depend on the presence of both photosystems i and ii; the light-independent reactions require only photosystem i. d the light-dependent reactions produce atp and nadph; the light-independent reactions use energy stored in atp and nadph.

D: The light-dependent reactions produce ATP and NADPH; the light-independent reactions use energy stored in ATP and NADPH.

Explanation:

Photosynthesis is a biological process during which green plants synthesize glucose using inorganic raw materials such as water and carbon dioxide. It is a reaction that takes place in an organelle known as chloroplast, and it consists of 2 reactions;

While the light dependent reaction cannot proceed without light availability, the light independent reaction can proceed both in the presence or absence of light.

Hence, the correct option is D.
