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.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
