Enzyme Quiz

At high temperatures, the rate of enzyme action decreases because the increased heat......

• neutralizes the acids and bases in the system

• alters the shape of the active site of the enzyme

• increases the concentration of the enzyme

• changes the pH of the system

Enzymes are important for the body because they

• increase the activation energy needed for a chemical reaction.

• keep the activation energy of a chemical reaction at a constant level.

• lower the activation energy needed for the chemical reaction.

• remove all of the activation energy needed for a chemical reaction.
