Current Question (ID: 11372)

Question:

Final acceptor in the Z-scheme of light reaction-

Options:

1. oxygen
2. NADPH
3. NADP⁺
4. ferredoxin

Solution:

The final acceptor in the Z-scheme of light reaction is NADP⁺ (nicotinamide adenine dinucleotide phosphate), which gets reduced to NADPH (nicotinamide adenine dinucleotide phosphate, reduced) by accepting high-energy electrons from the electron transport chain. In the light-dependent reactions of photosynthesis, light energy is harvested by chlorophyll pigments and converted into chemical energy in the form of ATP and NADPH. The electrons required to reduce NADP⁺ to NADPH are ultimately provided by water, which is oxidized to produce molecular oxygen.
