Enzymes

Front

What happens when enzymes are heated to a high temperature?

Back

The shape of the enzyme changes and it denatures.

Front

What is a competitive inhibitor?

Back

A substance that slows down a reaction by binding to the enzyme and preventing substrate interaction.

Front

Enzymes are an example of which type of biomolecule?

Back

Proteins.

Front

What is a catalyst?

Back

A substance that speeds up a chemical reaction without being consumed.

Front

What happens to an enzyme when it is denatured?

Back

It loses its shape.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes lower the activation energy required for reactions to occur.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and inhibitors.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature can increase activity up to a point, but excessive heat can denature the enzyme.

Front

What is the effect of pH on enzyme activity?

Back

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