Feedback inhibition example
WebFeedback inhibition occurs when the pathway's end product (here isoleucine) inhibits an upstream enzyme (indicated by red bar). In this example, isoleucine will bind to Threonine Deaminase (at the allosteric site) and prevent threonine from binding to this enzyme’s active site, effectively blocking this metabolic pathway.

WebJun 14, 2024 · 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. Feedback inhibition is a cellular control mechanism in which an enzyme’s activity is inhibited by the enzyme’s end product. This mechanism allows cells to regulate how much of an enzyme’s end product is produced. Most biochemical processes are complex and multi-step, requiring multiple enzymes to get from … See more 1.
