grin007 [14]

Answer: Option B) allosteric activation

Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation

Explanation:

Some enzymes have more than one active site. The other site(s) is called allosteric site.

In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.

ATP + H2O ---> ADP + Pi + free energy
