Answer to Question 1

D

Answer to Question 2

Carbohydrate digestion begins in the mouth with the action of amylase in the saliva on starch in the food. The action of amylase continues until stomach acids deactivate this enzyme. The arrival of food in the small intestine stimulates the release of another enzyme, pancreatic amylase, which further breaks down starch molecules into the disaccharides maltose, lactose, and sucrose. Then brush border enzymes (maltase, lactase, and sucrose) in the microvilli break the disaccharides into the monosaccharides glucose, galactose, and fructose. These monosaccharides are absorbed into the bloodstream and transported to the liver, where the fructose and galactose are converted to glucose, which is either stored in the liver or transported in the blood for delivery to your cells. The fiber continues down to the large intestine, where some of it is metabolized by bacteria in your colon. The majority of the fiber is eliminated in stool.
