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

Solution: The NADP reductase enzyme is found on the stroma side of the grana thylakoids. The stacks of thylakoids are known as grana. The figure depicts a single thylakoid, which indicates the position of the NADP reductase enzyme. NADP is converted to NADPH by this enzyme.

  1. Outer side of thylakoid membrane (Grana-lamella)

ATP is synthesized using the proton gradient generated by proton pumping during the electron transport chain. Through the membrane protein, protons move down their concentration gradient into the matrix. As a result of the breakdown of the protein gradient, NADH and ATP are produced.
