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.
