Answer: D. reduces the activation energy for the reaction it catalyzes.
Explanation:
The enzyme amylase is the enzyme which functions optimally in the environment. The enzyme amylase in the saliva functions in break down of starch which is a polysaccharide into small sugars. In this situation, the amylase is the enzyme and the starch is the substrate also the small sugar molecules are the products. Â
When the enzyme amylase binds to the substrate, then enzyme-substrate complex forms. The formation of this complex lowers the activation energy of the reaction and promotes the rapid progression of the reaction.
