Henry eats rice for lunch, which contains starch. Which enzyme catalyzes the reaction that takes place and which product is the
result of this reaction? A. Amylase catalyzes the reaction; glucose is the product
B. Pepsin catalyzes the reaction; lactase is the product
C. Lactate dehydrogenase catalyzes the reaction; lactate is the product

The answer is A. The digestion of carbohydrates such as starch begin in the mouth. The enzyme amylase is contained in saliva. The enzyme hydrolyzes starch to sugars by breaking the glycosidic bonds in the starch molecules. The same enzyme is produced by the pancreas breaking the sugars further down to their final elements which is glucose before absorption.
