What is the Role of Phosphofructokinase in Glycolysis

Question

What is the role of phosphofructokinase in glycolysis?
A) It converts fructose into fructose 1-phosphate.
B) It converts fructose 1-phosphate into fructose 1,6-bisphosphate.
C) It converts fructose 1,6-bisphosphate into glucose 1,6-bisphosphate.
D) None of these are correct.

Accepted Answer

Phosphofructokinase is an enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate, a crucial step in glycolysis. It is regulated by ATP, citrate, and other factors to control the rate of glycolysis. Therefore, choice B is the correct answer.
