Which reaction does not use glucose as a reactant to produce ATP?

Question

1. Photosynthesis

2. Fermentation

3. cellular respiration

4. Glycolysis

Answer 1

Answer: Photosynthesis

Photosynthesis does not use glucose as a reactant to make ATP. Photosynthesis is the process in which plants turn light, water, and carbon dioxide to make glucose (therefore, glucose is a product, not a reactant). After the glucose is produced by photosynthesis, cellular respiration turns it into ATP.
