Binds allosteric regulators of the enzyme.
Is involved in the catalytic reaction of the enzyme.
Digests the products of the catalytic reaction.
Is inhibited by the presence of a coenzyme or a cofactor.
Some enzymes change their structure when activators bind to the enzyme.
A competitive inhibitor can outcompete the substrate for the active site.
The binding of the substrate changes the shape of th enzyme's active site.
The active site creates a microenvironment ideal for the reaction.
Enzymes that require a cofactor or ion for catalysis speed up more appreciably than if the enzymes act alone.
Enzyme function is increased if the three-dimensional structure or conformation of an enzyme is altered.
Enzyme function is independent of physical and chemical environmental factors such as pH and temperature.
Enzymes increase the rate of chemical reactions by lowering activition energy barriers.
