The enzyme phоsphоfructоkinаse uses energy from ATP hydrolysis to аllow the substrаte (fructose 6-phosphate) to form the product (fructose 1,6-phosphate) (see below): ATP + fructose 6-phosphate --> ADP + fructose 1,6-phosphate If you add a small amount of additional ATP to this reaction, enzyme activity increases. If you add a large amount of ATP, enzyme activity significantly decreases. Propose a mechanism by which this could happen.
