Front

What is denaturation in relation to enzymes?

Back

The process where an enzyme loses its functional shape due to external stress.

Front

What is the role of the active site in an enzyme?

Back

It is the region where substrate molecules bind and undergo a chemical reaction.

What is the difference between a monomer and a polymer?

Back

A monomer is a single subunit, while a polymer is a chain of monomers.
