Warm-up: Macromolecules and Enzymes

Front

What are enzymes?

Back

Biological catalysts that speed up chemical reactions in living cells by lowering the activation energy.

How do enzymes increase the rate of a chemical reaction?

Back

By reducing the activation energy required for the reaction to occur.

Front

What are proteins made of?

Back

Monomers called amino acids.

Front

What is the function of the active site of an enzyme?

Back

The region where substrate molecules bind and undergo a chemical reaction.
