Enzymes

Front

What is the function of an enzyme?

Back

Enzymes speed up chemical reactions.

Front

True or False: An enzyme can only be used once in a chemical reaction.

Back

False. Enzymes can be used multiple times.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What are enzymes made of?

Back

Enzymes are proteins.

Front

What is a substrate?

Back

A substrate is the reactant that an enzyme acts upon.

Front

What happens to an enzyme after a reaction?

Back

The enzyme remains unchanged and can catalyze another reaction.

Front

What is the role of temperature in enzyme activity?

Back

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

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its structure and function due to extreme conditions.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases enzyme activity.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to another part of the enzyme.
