What is the main role of enzymes in biological reactions?

• To slow down reactions

• To change the products of reactions

• To speed up reactions

Why are enzymes considered catalysts?

• They are consumed during the reaction.

• They can be used repeatedly in reactions.

• They change the type of products formed.

• They require high temperatures to function.

What happens to an enzyme if its environment changes significantly from its ideal pH or temperature?

• It becomes more efficient.

• It changes its substrate.

• It becomes denatured and loses its function.

• It starts producing different products.
