Question: why is pfk important in glycolysis?
Answer: Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7. 1.11) of glycolysis. ... PFK is able to regulate glycolysis through allosteric inhibition, and in this way, the cell can increase or decrease the rate of glycolysis in response to the cell's energy requirements.
