mention the secretory gland and and functions of salivary amylase, pepsin, bilejuice, trypsin, lipase, enzymes in intestinal juices
Answers
Explanation:
secretary gland salivary is a saliva
Answer:
1. The intermediate gastric glands produce most of the digestive substances secreted by the stomach.
2.Salivary amylase initiates starch hydrolysis in the mouth, and this process accounts for not more than 30% of total starch hydrolysis. Because salivary amylase is inactivated by an acid pH, no significant hydrolysis of carbohydrates occurs in the stomach.
3. Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.
4. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
5. Trypsin is a proteolytic enzyme, important for the digestion of proteins. In humans, the protein is produced in its inactive form, trypsinogen, within the pancrease. Trypsinogen enters the small intestine, via the common bile duct, where it converted to active trypsin.
6.Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach.
7. Enzymes are globular proteins that control biological reactions. Digestive enzymes speed up the breakdown (hydrolysis) of food molecules into their 'building block' components. These reactions occur outside of the cells lining the gut.
