How are carbohydrates digested?

Answer 1

Starch digestion begins in the mouth. As food does not remain long in the mouth, only a little starch is digested by salivary amylase to maltose. No digestion of carbohydrates occurs in the stomach; only proteins are digested in the stomach. In the small intestine, starch is digested by pancreatic amylase into maltose, which is digested by maltase into glucose. Lactose is digested by lactase into glucose and galactose. Sucrose is digested by sucrase into glucose and fructose.The end products of carbohydrate digestion are simple sugars (glucose, fructose, and galactose) which can be absorbed. Cellulose is not digested in the humans' gut.
Yes.

Answer 2

Carbohydrate digestion begins in your mouth and proceeds through the digestive tract, as most carbohydrates are broken down into their simplest forms for use as fuel. Insoluble fiber is eliminated through excretion.

Breaking up the long polysaccharide chains of complex carbohydrates begins in your mouth, with the enzyme salivary amylase. Chewing physically breaks carbohydrates into smaller pieces, creating more surface area for salivary amylase to begin working. After you chew, you swallow the carbohydrates, which pass through your esophagus into your stomach, where stomach acid stops the effectiveness of salivary amylase. No additional carbohydrate digestion occurs until the mixture moves from your stomach into your small intestine.

Your pancreas releases an enzyme called pancreatic amylase into your small intestine, where it continues breaking down long saccharide chains into disaccharides, or dual-molecule sugars such as sucrose. Additional enzymes, including lactase, maltase, and sucrase, then break disaccharides down into monosaccharides, or single-molecule sugars such as glucose. These monosaccharides are absorbed by the villi, small finger-like protrusions in the intestine. They move to your liver, where they are stored as fuel to be used by your body.

Answer 3

carbohydrates are broken down by enzymes in the stomach which makes them into small soluble particles.

Answer 4

carbohydrates digest both mechanically and chemically in the mouth and in the stomach

Answer 5

In the cytoplasm, then the mitochondria of (aerobic) cells.
