To compare: The response of the given isozymes to the three effectors and discuss the possible implications of their different responses. Concept introduction: Phosphofructokinase-1 is the most important regulatory enzyme present in the glycolytic pathway. This is an allosteric enzyme made up of subunits that are demonstrated by many activators and inhibitors. In the liver, PFK-1 catalyzes the step of glycolysis in which the conversion of fructose-6-phosphate and ATP is converted into fructose-1, 6-bisphosphate, and ADP. In the brain, PFK-1 is also the regulatory isozyme.
