Enzymes

Front

What do enzymes speed up in chemical reactions?

Back

Enzymes speed up reaction rates by lowering the activation energy.

Front

What is the primary function of an enzyme?

Back

The primary function of an enzyme is to speed up chemical reactions.

Front

What is the term for the specific region on an enzyme where substrates bind?

Back

Active site.

Front

What do we call the molecules that enzymes act upon?

Back

Substrates.

Front

What suffix do most enzymes end with?

Back

-ase.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy, making it easier for the reaction to occur.

Front

What happens to enzymes after they catalyze a reaction?

Back

Enzymes are not consumed in the reaction and can be used repeatedly.

Front

What is a substrate-enzyme complex?

Back

A substrate-enzyme complex is formed when a substrate binds to the active site of an enzyme.

Front

What is the role of temperature in enzyme activity?

Back

Temperature affects enzyme activity; each enzyme has an optimal temperature range.
