Enzymes

Enzymes are capable of increasing the rate of a chemical reaction within a living cell.  Enzymes accomplish this through which of the following means?

• reducing the number of products   
• reducing the activation energy
• increasing the temperature of the cell
• increasing the concentration of reactants
