Answer 1

The main purpose of the light-dependent reactions is **to energize electrons**. These reactions occur in the thylakoid membranes of chloroplasts and use light energy to generate ATP and NADPH, which are crucial for the subsequent light-independent reactions (Calvin cycle) that synthesize glucose. While oxygen is produced as a byproduct during these reactions, the primary goal is to convert light energy into chemical energy by energizing electrons.
