Q
Q: How many molecules of ATP are produced in the light-dependent reactions for each molecule of glucose synthesized?
Solution: A total of 18 ATP molecules are produced for each glucose molecule synthesized.
Steps: 7
Step 1: Understand that glucose is produced during photosynthesis, which occurs in plants.
Step 2: Know that photosynthesis has two main stages: light-dependent reactions and light-independent reactions (Calvin cycle).
Step 3: Focus on the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts.
Step 4: Recognize that during the light-dependent reactions, sunlight is used to split water molecules, producing oxygen and energy carriers.
Step 5: Identify that the energy carriers produced are ATP and NADPH.
Step 6: Learn that for every molecule of glucose synthesized (which requires multiple cycles of the Calvin cycle), a total of 18 ATP molecules are generated from the light-dependent reactions.
Step 7: Conclude that for each glucose molecule synthesized, 18 ATP molecules are produced in the light-dependent reactions.
