Question

level 3 q4 what is the energy molecule that is used during photosynthesis? a. h₂o b. nadph c. mitochondria d. atp diagram showing phosphate groups, ribose, adenine (structure of a molecule) options: a. h20 b. nadph c. mitochondria d. atp

Explanation:

• Option A: $\ce{H_2O}$ is a reactant in photosynthesis, providing electrons and oxygen, not an energy molecule.
• Option B: NADPH is an electron carrier and provides reducing power in photosynthesis, not the primary energy molecule used directly for energy - related reactions in the same way as ATP.
• Option C: Mitochondria are organelles involved in cellular respiration, not a molecule used in photosynthesis.
• Option D: ATP (adenosine triphosphate) is the energy - carrying molecule that is used to provide energy for the chemical reactions during the Calvin cycle (the light - independent stage of photosynthesis) to convert carbon dioxide into glucose.

Answer:

D. ATP
