Question

which of the following does not occur during photosynthesis? (1 point)
adp is used to make atp
carbon dioxide is used to make sugar
water is used to make nadph
oxygen is used to make carbon dioxide

Explanation:

During photosynthesis, ADP is converted to ATP in the light - dependent reactions. Carbon dioxide is fixed and used to make sugar (glucose) in the Calvin cycle (light - independent reactions). Water is split in the light - dependent reactions, and electrons from water are used to make NADPH. However, oxygen is a by - product of photosynthesis (from the splitting of water) and is not used to make carbon dioxide. Carbon dioxide is taken in from the atmosphere and used in the synthesis of organic compounds.

Answer:

Oxygen is used to make carbon dioxide
