WebEnzymes are specific to substrates as they have an active site which only allow certain substrates to bind to the active site. This is due to the shape of the active site and any … WebEnzymes are reusable. Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.

WebSep 1, 2024 · This is because allosteric enzymes have multiple active sites. These multiple active sites exhibit the property of cooperativity, where the binding of one active site affects the affinity of other active sites on the enzyme. As mentioned earlier, it is these other affected active sites that result in a sigmoidal curve for allosteric enzymes. ... WebEnzymes have an active site that provides a unique chemical environment, made up of certain amino acid R groups (residues) in a particular orientations and distance from one another. This unique environment is well-suited to convert particular chemical reactants for that enzyme, called substrates, into unstable intermediates (transition states).
