Which of the following is a key benefit of the light-dependent reactions in photosynthesis?

A.D) The release of O2 as a byproduct.

B.A) The production of glucose.

C.B) The regeneration of NAD+.

D.C) The synthesis of ATP and NADPH.

Explanation

Core Concept

The light-dependent reactions are crucial for synthesizing ATP and NADPH, which are then used to drive the light-independent reactions and produce glucose. This is a key benefit of the light-dependent reactions, allowing plants to convert light energy into chemical energy. Options A, B, and D are incorrect because glucose is produced in the light-independent reactions, NAD+ is reduced to NADPH in the light-dependent reactions, and O2 is released in the light-independent reactions.
