Final answer:
A substance that alters the rate of an enzymatic reaction by binding to the enzyme at a site other than the active site is called a non-competitive inhibitor. Non-competitive inhibitors bind to an allosteric site on the enzyme, which is a location other than the active site.
Step-by-step explanation:
A substance that alters the rate of an enzymatic reaction by binding to the enzyme at a site other than the active site is called a non-competitive inhibitor. A substance that alters the rate of an enzymatic reaction by binding to the enzyme at a site other than the active site is called a non-competitive inhibitor. Non-competitive inhibitors bind to an allosteric site on the enzyme, which is a location other than the active site.
Non-competitive inhibitors bind to an allosteric site on the enzyme, which is a location other than the active site. When a non-competitive inhibitor attaches to the allosteric site, it changes the shape of the enzyme, affecting the configuration of the active site and decreasing its affinity for the substrate.
