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? Amylase catalyzes the reaction; glucose is the product Pepsin catalyzes the reaction; lactase is the product Lactate dehydrogenase catalyzes the reaction; lactate is the product
Amylase catalyzes the reaction; glucose is the product
Explanation:
In the process of digestion, polysaccharides like starch are broken down into monosaccharides before being absorbed. Digestion of starch is catalysed by amylase enzymes which are salivary amylase and pancreatic amylase. Salivary amylase begins digestion of starch inside mouth during chewing process. The digestion is further carried out by pancreatic amylase in small intestine. The starch is hydrolysed in digestion process and the products are glucose, maltose, maltotriose and α-dextrins. Disaccharides like maltose are further converted into monosaccharides by enzymes like maltase which are present in brush border of small intestinal cells.
