Question

what is released as a byproduct of photosynthesis? *
sunlight
glucose
oxygen
carbon dioxide
atp & nadph
water

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose (energy - rich sugar) and oxygen. Sunlight is an input (not a by - product). Glucose is the main product. Carbon dioxide and water are reactants. ATP and NADPH are energy - carrying molecules produced during the light - dependent reactions but are not by - products in the sense of being released as an extra. Oxygen is released as a by - product when water is split during the light - dependent reactions of photosynthesis.

Answer:

oxygen
