Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is a substrate?

Back

A substrate is any substance that is acted upon by an enzyme.

Front

Do enzymes act on many different substrates?

Back

False, enzymes are specific to their substrates.

Front

What is the primary function of an enzyme?

Back

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

Front

What happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, it loses its shape and functionality.

Front

How do enzymes speed up reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What is activation energy?

Back

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

Front

What is a coenzyme?

Back

A coenzyme is a non-protein molecule that assists enzymes in catalyzing reactions.

Front

Can enzymes be reused?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.
