What molecule is used by the enzyme ATP synthase to form ATP? ADP NADH ATP FADH 2

ATP synthase takes ADP and adds on a phosphate to make ATP. Therefore, the answer is ADP.

Answer;

ADP

Explanation;

-ATP molecule actsas the major energy molecule used by the cells. ATP synthase located in the inner membrane of the mitochondria, catalyses the formation of ATP, as a result of protons concentration gradient.

-The enzyme generates ATP from adenosine diphosphate and an inorganic phosphate through a process called oxidative phosphorylation, which is the process by which enzymes oxidize nutrients to form ATP.
