The enzyme amylase is found in saliva and assists with the break down of starch into glucose. Explain how this occurs without affecting the chemical makeup of the amylase.
Amylase bonds to the starch to speed up the reaction and detaches itself when complete, without being affected.
Amylase does not take place in the starch reaction, but raises the temperature of the saliva to speed up the reaction.
Amylase changes starch into a vapor which increases the reaction rate, but is recreated by the glucose.
Amylase transfers all of its energy to the starch molecules to speed the reaction, but does not take place in the reaction.
