Sever21 [200]

Answer;

C. A decrease in the formation of ATP

Explanation;

-During the first stage of photosynthesis NADPH is created. It involves two set of molecules, that is photosystem I and photosystem II, which absorb sunlight, then convert it to chemical energy, and transfer it to electrons.

-Outside factors may cause the plant's pH level to drop during photosynthesis. When this happens, the shape of the proteins may be altered within the two photosystems and cause a decrease in the formation of NADPH, thus adversely affecting efficient photosynthesis, and cause a decrease in the formation of ATP.
