Protease.

Front

What is the role of coenzymes?

Back

Molecules that assist enzymes in catalyzing reactions.

Front

What happens to enzymes after a reaction?

Back

They remain unchanged and can be used repeatedly.

Front

What is enzyme specificity?

Back

The ability of an enzyme to choose exact substrates from a group of similar chemical molecules.
