Explain how enzymes are regulated by feedback inhibition.

Enzymes can be regulated by a mechanism called feedback inhibition, where the

product of the reaction acts as

the repressor. Enzyme inhibition can occur in two ways. Competitive inhibitors

compete with the substrate for the

same binding site. Noncompetitive inhibitors can bind to the enzyme at the

allosteric site, changing the shape of

the enzyme and making it unable to bind to the substrate.
