Trypsin is an enzyme that is secreted into the small intestine to further break down peptides into their amino acids. If trypsin is mixed in with a solution of starch molecules, which of the following is most likely to happen?

• Trypsin will break down the starch if the pH is within the optimum range.

• Trypsin will break down the starch if the temperature is within the optimum range.

• Trypsin will not break down the starch because enzymes are substrate specific.

• Trypsin will not breakdown the starch if the solution is not in the small intestine.

In what ways do enzymes help a cell carry out its chemical reactions?

• Enzymes lower the amount of reactants needed for the reaction to occur.

• Activation energy and the rate of reaction are both increased by enzymes.

• Enzymes speed up chemical reactions by lowering the activation energy needed.

• Enzymes slow the reaction down by increasing the amount of energy produced.
