Question

Explain the process of digestion in small intestine

Answer 1

Explanation:

Chemical Digestion in the Small Intestine

The hormone secretin also causes bicarbonate to be released into the small intestine from the pancreas to neutralize the potentially harmful acid coming from the stomach. The three major classes of nutrients that undergo digestion are proteins, lipids (fats), and carbohydrates

Answer 2

$\huge\red{\mathbb{♡Answer♡}}$

In the first part of the small intestine, the secretion of the liver called bile and the pancreatic juice are received. The bile salts break down the large globules of fat into smaller globules. This is called emulsification. The bile also makes the food alkaline so that the pancreatic enzymes can act. The pancreatic enzymes contain trypsin for digesting proteins and lipase for digesting fats.

☯The walls of the small intestine secrete intestinal juices which finally digest as follows :

Proteins → amino acids

Fats → fatty acids and glycerol

Carbohydrates → glucose
