WebEach protein has specific function in our body. The structure of the protein has a very important role in its function. ... Molecules with appropriate shape and appropriate groups can bind to the active site of the protein molecule. The mechanism is as simple as lock and key, as the particular lock opens with the only particular key, the ... WebSome molecules very similar to the substrate for an enzyme may be bound to the active site but be unable to react. Such molecules cover the active site and thus prevent the binding of the actual substrate to the site. This inhibition of enzyme action is of a competitive nature, because the inhibitor molecule actually competes with the substrate for the … north andover ma town assessor

One can then locate the active sites on an enzyme by following where the analog binds. Active Site vs. Regulatory Site An enzyme, for example ATCase, contains two distinct subunits: an active site and a regulatory site. The active site is the catalytic subunit, whereas the regulatory site has no catalytic activity. how to replace a handle on a garden tamper
