Select all of the statements about enzymes that are true.

• Enzymes are destroyed when they are used and must be synthesized for each reaction

• Enzymes are made of protein

• Enzymes are specific because of their shape and catalyze only certain reactions

• Enzymes lower the activation energy of reactions
