Question 4. What is the function of digestive enzymes? 

Ans. Digestive enzymes such as amylase, lipase, pepsin, trypsin, etc. help in the breaking down of complex food particles into simple ones. These simple particles can be easily absorbed by the blood and thus transported to all the cells of the body

Question 5. How is the small intestine designed to absorb digested food?

Ans. To digest the carbohydrates, fats and proteins, the small intestine receives the secretions of the liver and pancrease. The acidic food coming from the stomach is made alkaline for the action of pancreatic enzymes. The liver secretions have bile juice. The bile salts break the larger fat globules into the smaller one for the effective action of enzymes (emulsification of fats). The walls of small intestine contain glands which secrete intestinal juice. This contains enzymes to convert: Proteins àamino acids Complex Carbohydrates àglucose Fats àfatly acids & glycerol The digested food components are absorbed into the walls of the intestine.
