Describe the role of hexokinase in glucose metabolism.
Adi S.
Hexokinase is an enzyme that binds specifically to glucose and converts it into glucose 6-phosphate. the activity of hexokinase is suppressed by glucose 6-phosphate, which binds to hexokinase at a location that is distinct from the active site. this is an example of what?
Sri K.
Glucokinase and hexokinase are two enzymes that phosphorylate glucose to make glucose-6-phosphate. Glucokinase is induced by insulin, while hexokinase is not affected by insulin. Glucokinase is not affected by glucose-6-phosphate levels, but hexokinase is inhibited by glucose-6-phosphate. Glucokinase also has a much higher km for glucose than hexokinase. What is the benefit of having these regulatory and glucose affinity differences between the two enzymes?
