Question

a. NADP reductase enzyme is located on _________________.
b. Breakdown of proton gradient leads to release of_________________.

Answer 1

NADP reductase:

NADP reductase enzyme is located on the thylakoid membrane. In light reaction, it reduces NADP to NADPH.

Final answer: Thylakoid membrane

ATP synthesis:

• In light reaction, a proton gradient is created across the thylakoid membrane making the thylakoid lumen acidic.
• This proton gradient is a driving force for the synthesis of ATP.
• As the proton gradient develops across the thylakoid membrane, protons pass through the ATP synthase present within the thylakoid membrane.
• This leads to the production of ATP molecules.

Final answer: ATP molecules
