Current Question (ID: 11345)

Question:

Where does exactly the NADP reductase enzyme located?

Options:

1. Thylakoid lumen
2. Thylakoid luminal side of membrane
3. Stromal side of thylakoid membrane
4. Cytoplasm

Solution:

The NADP reductase enzyme is located on the stromal side of the thylakoid membrane in chloroplasts. It plays a key role in the light-dependent reactions of photosynthesis by catalyzing the transfer of electrons from ferredoxin to NADP⁺, producing NADPH, which is an important reducing agent in many biochemical processes. Therefore, the correct answer is option 3, "Stromal side of thylakoid membrane." Options 1 and 2 refer to the lumen side of the thylakoid membrane, where the protons accumulate to form a proton gradient during the light-dependent reactions. Option 4, "Cytoplasm," is not correct because chloroplasts are organelles found within plant cells and are not located in the cytoplasm.
