What role does lactase play in the digestion of carbohydrate in milk and how might this change as we age?
(91) 
VerifiedLactase is an enzyme made by the small intestine. It splits the disaccharide lactose into its component monosaccharides, glucose and galactose, which are then absorbed by the body. About 75 percent of the world's population lose their ability to produce lactase as they age. This results in lactose intolerance, a condition that causes varying degrees of discomfort when consuming lactose-containing products, due to the undigested lactose in the intestinal tract.

Describe the tasks of the various body systems in breaking down carbohydrate into glucose to fuel the cells' work.
(75) Verified1. Fibre, starch, some monosaccharides, and disaccharides from food leave the mouth and enter the stomach via the esophagus, passing through to the small intestine. Some of the starch is partially broken down by an enzyme from the salivary glands (salivary amylase) before it reaches the small intestine.2. The enzyme pancreatic amylase from the pancreas digests most of the starch to disaccharides.3. The enzymes (lactase, sucrase, and maltase) on the surface of the intestinal wall cells split disaccharides to monosaccharides.4. Monosaccharides enter capillaries and then are delivered to the liver via the portal vein.5. The liver converts galactose and fructose to glucose.6. Fibre and resistant starch travel unchanged to the colon.
