2.9.1 Enzyme Action: The Induced-Fit Model

Enzyme specificity appears to be a function of the enzyme's

active site.

The specificity of the active site of an enzyme is determined by the

amino acid sequence.

Non-enzymatic molecules that are close in shape to the enzyme substrate, but are non-reactive, are

competitive inhibitors.

Enzymes bind to particular substrates because

the shape and charge of the active site is complementary to the substrate.

True or false? The active site is a rigid pocket in the enzyme that is perfectly shaped to match the shape of the substrate molecule.

FALSE
