What is feedback inhibition? Describe one example of feedback inhibition.

n. An inhibition of activity due to the production of an end product of the action. feedback mechanism.

An example of feedback inhibition is the inhibition of the activity of the enzyme hexokinase by glucose 6-phosphate in glycolysis. This enzyme catalyses conversion of glucose into glucose 6-phosphate but as the reaction proceeds, increase in concentration of glucose 6-phosphate inhibits the activity of hexokinase.
