Detailed explanation-1: -The allosteric inhibitor binds to an enzyme at a site other than the active site. The shape of the active site is altered so that the enzyme can no longer bind to its substrate.
Detailed explanation-2: -Competitive enzyme inhibitors possess a similar shape to that of the substrate molecule and compete with the substrate for the active site of the enzyme. This prevents the formation of enzyme-substrate complexes. Therefore, fewer substrate molecules can bind to the enzymes so the reaction rate is decreased.
Detailed explanation-3: -(EN-zime in-HIH-bih-ter) A substance that blocks the action of an enzyme. Enzymes help speed up chemical reactions in the body and take part in many cell functions, including cell signaling, growth, and division. In cancer treatment, enzyme inhibitors may be used to block certain enzymes that cancer cells need to grow.
Detailed explanation-4: -There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and prevent substrate from binding. They can be, however, dissociated with the addition of more substrates.
Detailed explanation-5: -Competitive inhibition occurs when the inhibitor binds at the same site as the substrate.
