Enzyme Kinetics Quiz

Enzyme kinetics is the study of the rates of enzyme-catalysed chemical reactions.

Studying enzyme kinetics can reveal the catalytic mechanism of an enzyme, its role in metabolism, how its activity is controlled, and how a drug or a modifier might affect the rate.

An enzyme is typically a protein molecule that promotes a reaction of another molecule, its substrate.
