Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the active site of an enzyme?

Back

The specific region on an enzyme where the substrate binds.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What are products in a chemical reaction?

Back

The substances that are produced as a result of a chemical reaction.

Front

What is the primary function of enzymes?

Back

To speed up reactions by lowering the activation energy required.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the optimal temperature for enzyme activity?

Back

The temperature at which an enzyme functions most efficiently.

Front

What is the optimal pH for enzyme activity?

Back

The pH level at which an enzyme is most active.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases activity up to a point, after which the enzyme may denature.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can catalyze subsequent reactions.
