The enzyme which makes ATP is called ATP synthase, or ATPase, and sits on the mitochondria in animal cells or chloroplasts in plant cells. Walker first determined the amino acid sequence of this ...

Thus, the F- and V-type ATPases are two distinct, although related, molecular machines in which the action of multiple parts is tightly coordinated to achieve coupling between ion current and ATP ...

The gradient created by this drives hydrogen back through the membrane, through ATP synthase. As this happens, the enzymatic activity of ATP synthase synthesiszes ATP from ADP. Mitochondria are ...
