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.
A. feedback inhibition.
B. competitive inhibition.
C. cofactor binding.
D. allosteric activation.
A. feedback inhibition.
In this case, the product of the reaction, glucose 6-phosphate, is feeding back to inhibit the enzyme that catalyzes the reaction, hexokinase. As a result, this is an example of feedback inhibition.
