Q
Q: What role does NADPH play in photosynthesis?
Solution:
NADPH acts as an electron donor in the Calvin cycle, providing the reducing power for carbon fixation.
Steps: 7
Show Steps
Step 1: Understand that photosynthesis is the process plants use to convert sunlight into energy.
Step 2: Learn that there are two main stages in photosynthesis: the light-dependent reactions and the Calvin cycle.
Step 3: Know that during the light-dependent reactions, sunlight is captured and used to create energy-rich molecules, including NADPH.
Step 4: Recognize that NADPH is a molecule that carries electrons and energy.
Step 5: Understand that in the Calvin cycle, which is the second stage of photosynthesis, plants need energy to convert carbon dioxide into glucose.
Step 6: Realize that NADPH provides the necessary electrons (reducing power) to help in this conversion process, known as carbon fixation.
Step 7: Conclude that without NADPH, the Calvin cycle would not be able to produce glucose efficiently.
