What is the role of active site of an enzyme?

In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).

Just so, why is the shape of the active site of an enzyme important?

Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules. Amino acids that attracted each other may no longer be.

Also, what are the functions of active sites? Structural Biochemistry/Enzyme/Active Site. An active site is the part of an enzyme that directly binds to a substrate and carries a reaction. It contains catalytic groups which are amino acids that promote formation and degradation of bonds.

Also to know is, what is responsible for the shape of the active site?

Usually, each subunit of an enzyme has one active site capable of binding substrate. The characteristics of an enzyme derive from the sequence of amino acids, which determine the shape of the enzyme (i.e., the structure of the active site) and hence the specificity of the enzyme.

How do you determine the active site of an enzyme?

The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). A substrate enters the active site of the enzyme.
