Enzymes

Front

What type of molecule are enzymes?

Back

Enzymes are proteins.

Front

What do enzymes reduce in a chemical reaction?

Back

Enzymes reduce the activation energy needed to start a reaction.

Front

What is the primary purpose of an enzyme?

Back

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

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 is a substrate in the context of enzymes?

Back

A substrate is the reactant that an enzyme acts upon.

Front

How can an inhibitor affect enzyme activity?

Back

An inhibitor can prevent an enzyme from functioning correctly by changing its active site.

Front

What is activation energy?

Back

Activation energy is the minimum energy required to start a chemical reaction.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their structure and function.

Front

What is the relationship between enzymes and catalysts?

Back

Enzymes are biological catalysts that speed up chemical reactions without being consumed.

Front

What role does pH play in enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.
