An enzyme cаlled phоsphоfructоkinаse binds а substrate called fructose-6-phosphate (F6P) and catalyzes a reaction to form a product. The activity of this enzyme depends on the presence of a molecule called adenosine triphosphate, or ATP. The figure shows the relationship between the concentration of F6P and the activity of enzymes, in either the presence or absence of ATP. The activity of enzymes was measured as the rate at which products were formed (also called the rate of reaction). Which statement could explain the effect of ATP on the activity of this enzyme?
