Which of the following is NOT a product of the light-dependent reactions of photosynthesis?

In the light-dependent reactions of photosynthesis, the primary products generated are ATP, NADPH, and oxygen. These reactions occur in the thylakoid membranes of chloroplasts and rely on light energy to convert water and other substrates into these crucial molecules. ATP and NADPH serve as energy carriers, while oxygen is released as a byproduct when water is split during this process.

Glucose, however, is not produced during the light-dependent reactions; instead, it is synthesized during the subsequent light-independent reactions, commonly known as the Calvin cycle. This pathway takes place in the stroma of the chloroplasts and uses ATP and NADPH produced in the light-dependent phase to convert carbon dioxide into glucose. Therefore, glucose is not a product of the light-dependent reactions, making it the correct answer in this context.
