Final answer:
Glucose is not an output of the light-dependent reactions of photosynthesis; those reactions produce ATP, NADPH, and oxygen, while glucose is formed during the light-independent reactions.
Step-by-step explanation:
The product that is not an output of the light-dependent reactions of photosynthesis is B) Glucose. The light-dependent reactions, which occur in the thylakoid membranes of chloroplasts, use light energy to produce two types of chemical energy: ATP and NADPH. They also produce oxygen as a byproduct of splitting water molecules (H2O). Conversely, glucose is synthesized during the light-independent reactions, also known as the Calvin cycle or dark reactions, which use the ATP and NADPH generated in the light-dependent reactions to convert carbon dioxide (CO2) into glucose.
