• reducing the activation energy

• increasing the temperature of the cell

• increasing the concentration of reactants

What 3 letters do enzymes typically end in?

• -ose
• -ase
• -ese
• -tic

After the enzyme and substrate bind together and perform the reaction, what does the substrate become?

• a substrate
• an enzyme
• a product
• an active site
