Answer: The correct answer is -
A. It has lost one electron.
Explanation:
NADPH acts as a reducing agent as it can donate electron to get converted to NADP+.
This means that NADP+ due to extra proton in its chemical structure, is an oxidised form of NADPH.
NADP+ is a significant molecule that is used in the movement of high energy electrons in several processes like photosynthesis.
Thus, when NADPH loses one electron, it produces NADP+.
