How are proteins absorbed in the intestines?

Answer 1

within the small intestine, a battery of ezymes completes the chemical digestion of virtually all the carbohydratesproteins, fats, and nuclieic acids in food. although both the small intestine and the pancreas contribute enzymes, most of the digestion that occurs in the small intestine is actually performed by pancreatic enzymes

Answer 2

Absorption is the movement of small molecules through the absorptive epithelial cells of the mucosa into the underlying blood and lymphatic vessels. All carbohydrates are absorbed as monosaccharides. Glucose and galactose are transported into absorptive cells of the villi by active transport. Fructose is transported by facilitated diffusion. Lipases break down triglycerides into monoglycerides and fatty acids. The fatty acids can be either short-chain fatty acids (with fewer than 10-12 carbons) or long-chain fatty acids. The short-chain fatty acids are absorbed via simple diffusion into absorptive cells of the villi and then pass into blood capillaries along with monosaccharides and amino acids. Bile salts emulsify the larger lipids, forming many micelles, tiny droplets that include some bile salt molecules along with the long-chain fatty acids, monoglycerides, cholesterol, and other dietary lipids.

Answer 3

Protein is broken down into amino acids which is broken down again into urea and stored in the liver. The urea is then filtered by the kidneys and stored in the bladder then passed out. Carbohydrates are broken down into glucose by the carbohydrase enzyme.

Answer 4

proteins - ammino acids

carbohydrates - glucose

fats - fatty acids & glycerol

Answer 5

Proteins--> amino acids.

Carbohydrates---> mono-saccharides (Simple sugars).

Fats---> glycerol and fatty acids.
