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 __________. feedback inhibition oxidative phosphorylation allosteric activation substrate-level phosphorylation.

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 _______. A. substrate-level phosphorylation. B. allosteric activation. C. oxidative phosphorylation. D. feedback inhibition.

A high concentration of ATP inhibits the enzymes that are responsible for glycolysis. Provide a mechanism to explain how the inhibition of these enzymes is influenced by the level of energy demand within the cell.
ATP is an allosteric inhibitor of phosphofructokinase that catalyses the third reaction of glycolysis. Which of the following statements best describes what occurs during this process? a. Feedback inhibition regulates respiration. b. The intermediates of glycolysis act as building blocks for other biochemical reactions. c. The concentration of substrates and product change the equilibrium of the reaction. d. ATP is continuously synthesised and hydrolysed back to ADP and Pi. e. ATP is both a substrate and product of glycolysis.
