Enzyme Quiz

What is the role of an enzyme in a chemical reaction?

• It is consumed by the reaction.

• It slows down the reaction.

• It acts as a catalyst and speeds up the reaction.

• It changes the products of the reaction.

Which of the following is a characteristic of enzymes?

• They are not specific to substrates.

• They are reusable and not consumed by the reaction.

• They are always consumed in the reaction.

• They can act on any chemical reaction.

What suffix is commonly found in the names of enzymes?

• -ose

• -ase

• -ine

• -ate

What is formed when an enzyme binds to its substrate?

• Enzyme-product complex

• Enzyme-substrate complex

• Substrate-product complex

• Enzyme-inhibitor complex

What is a characteristic of a specific enzyme?

• Works for multiple reactions

• Works for a specific reaction

• Cannot be reused

• Increases activation energy

What is activation energy?

• Energy released during a reaction

• Energy required to start a reaction

• Energy that decreases during a reaction

• Energy that is not needed for a reaction

How do enzymes affect activation energy?

• Increase activation energy

• Have no effect on activation energy

• Lower activation energy

• Eliminate the need for activation energy

What role does heat play in activation energy?

• Heat is not involved

• Heat decreases activation energy

• Heat is absorbed by reactant molecules

• Heat is released by reactant molecules

What effect do enzymes have on activation energy in a reaction?

• Enzymes increase activation energy.

• Enzymes have no effect on activation energy.

• Enzymes lower activation energy.

• Enzymes convert energy into products.
