Amoeba Sisters: Enzymes

What type of macromolecule are most enzymes?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

What is the specific region on an enzyme where a substrate binds called?

• Binding pocket

• Catalytic site

• Active site

• Reaction center

Why is the binding between an enzyme and its substrate considered very specific?

• The enzyme changes its shape to fit any substrate

• The active site is specifically shaped for a particular substrate

• Substrates are always larger than the active site

• Enzymes can bind to multiple types of substrates

What is the primary role of enzymes in biological reactions?

• To slow down reactions

• To provide energy for reactions

• To speed up reactions

• To change the products of reactions

Which enzyme is responsible for breaking down lactose?

• Amylase

• Protease

• Lipase

• Lactase

Why are enzymes referred to as catalysts?

• They are consumed during the reaction

• They are only used once

• They can be used repeatedly without being used up

• They change the type of products formed

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

• It becomes more efficient

• It changes into a different enzyme

• It becomes denatured and loses its function

• It starts producing new substrates
