NADP+ reductase accept electron from?
Correct answer: B. Ferredoxin
- A. Plastoquinone
- B. Ferredoxin
- C. Cytochrome complex
- D. Plastocyanin
Explanation
Ferredoxin is a small iron-sulfur protein that acts as an electron carrier in photosynthetic organisms.Ferredoxin receives electrons from PSI and transfers them to ferredoxin-NADP+ reductase, which catalyzes the reduction of NADP+ to NADPH. This step is crucial for the production of NADPH, which is used in the Calvin cycle for carbon fixation.
