Enzymes

What is the effect of enzymes on activation energy?

• Enzymes increase the activation energy required.

• Enzymes decrease the activation energy required.

• Enzymes have no effect on activation energy.

• Enzymes stop the reaction from occurring.

What is the primary function of an enzyme in a chemical reaction?

• To increase the energy of the reactants

• To decrease the energy of the products

• To lower the activation energy required

• To stop the reaction from occurring

Which part of the enzyme reaction is the place where the substrate binds?

• Product

• Active site

• Substrate

• Enzyme

What is the role of the active site in an enzyme reaction?

• It produces the product

• It binds to the substrate

• It is the enzyme itself

• It changes the substrate

What happens to the substrate after it binds to the enzyme?

• It becomes the active site

• It is converted into the product

• It remains unchanged

• It becomes the enzyme

What is the first step in the process of how an enzyme works?

• The products are released

• The enzyme breaks or bonds the substrate

• The substrate binds to the enzyme

• The enzyme is reused

What is the second step in the process of how an enzyme works?

• The products are released

• The enzyme breaks or bonds the substrate

• The substrate binds to the enzyme

• The enzyme is reused

What is the role of the active site in an enzyme?

• It releases the products

• It binds to the substrate

• It breaks the enzyme

• It forms the enzyme-substrate complex

What is the term for the combination of an enzyme and its substrate?

• Enzyme-product complex

• Enzyme-substrate complex

• Product

• Substrate

How can pH affect an enzyme?

• pH can speed up the enzyme.

• pH can denature the enzyme.

• pH has no effect on the enzyme.

• pH can slow down the enzyme.
