Q
Q: What is the significance of the light-dependent reactions for the dark reactions?
Solution: The light-dependent reactions produce ATP and NADPH, which are essential for the dark reactions to synthesize glucose.
Steps: 6
Step 1: Understand that photosynthesis happens in two main stages: light-dependent reactions and dark reactions.
Step 2: Know that light-dependent reactions occur in the presence of sunlight.
Step 3: Realize that during light-dependent reactions, sunlight is used to produce energy molecules called ATP and NADPH.
Step 4: Recognize that dark reactions, also known as the Calvin cycle, do not need sunlight directly but use the products from light-dependent reactions.
Step 5: Understand that ATP provides energy and NADPH provides reducing power for the dark reactions.
Step 6: Conclude that without ATP and NADPH from the light-dependent reactions, the dark reactions cannot effectively synthesize glucose.
