Explain three ways in which other molecules regulate enzymes
What will be an ideal response?
Enzymes can be inhibited by products of the reaction that bind to a site other than the active site. This
is called feedback inhibition or allosteric inhibition. Enzymes can be inhibited by molecules that
compete for access to the active site and when bound, block the substrate from entering the active site.
This is called competitive inhibition. Enzymes can also be activated or stabilized by reaction products
binding to a site other than the active site. This is called allosteric activation.
