Question

Given what you know about glycolysis and regulation of metabolism by pfk, what is the likely mechanism by which pfk activity differs depending on atp concentration?

Answer 1

Step-by-step explanation:

PFK is an allosteric enzyme and it is able to regulate glycolysis through allosteric inhibition. The cell can increase or decrease the rate of glycolysis. Example: a high ratio of ATP to ADP will inhibit PFK and glycolysis.

Regulation of metabolism pathways include regulation of an enzyme by increasing or decreasing its response to signal in a pathway. Glycolysis is a process in which one molecule of glucose is broken down into two molecules of pyruvic acid. The glycolysis process is a multi-step metabolic pathway.

Answer 2

The likely mechanisms by which pfk activity differs depending on atp concentration is that PFK is an allosteric enzyme that is inhibited by ATP and stimulated by AMP
