The Calvin cycle is the process by which:
  1. Carbon dioxide is fixed and converted into carbohydrates.
  2. Hydrogen ions are generated and used to make NADPH.
  3. Electrons become excited and are used to produce ATP.
  4. Oxygen is removed from water molecules and released as a gas.
Explanation
Correct Response: A. During photosynthesis, the Calvin cycle uses ATP and NADPH to incorporate carbon dioxide gas into carbohydrates. The production of NADPH (B) and ATP (C) and the release of oxygen gas (D) are all events that occur during the light reactions of photosynthesis, rather than during the Calvin cycle.
