Question

The light dependent reactions of photosynthesis take energy from sunlight and convert it into stored chemical energy. Which compounds are produced in the light-dependent reactions?

A) ADP and NADP +
B) ADP and NADPH
C) ATP and NADP +
D) ATP and NADPH

Answer 1

The correct answer will be option-D.

Step-by-step explanation:

Photosynthesis process proceeds in two phases: light-dependent reaction and independent reaction. The light-dependent reaction is necessary as it converts the light energy to chemical energy by capturing the light photons by photosystems.

Light causes excitation of the electrons from chlorophyll which travels down electron transport chain and produces the intermediate energy equivalents mainly ATP and NADPH. These ATP and NADPH are directly utilized in the second phase of the photosynthesis which forms the glucose molecule.

Thus, option-D is the correct answer.
