I. What is the role of the acid in our stomach? II. What is the function of digestive enzymes? |

Answer» i. HCl plays a major role in the process of digestion, as mentioned below: • It creates a medium of gastric juice acidic so that the enzyme pepsin digests the protein and kills the bacteria present in them. • HCl helps in the process of digestion by disintegrating complex large food molecules into simpler molecules. • Acid lowers the P H level in the stomach, which otherwise would lead to hypergastrinemia. ii. Digestive enzymes helps in digesting complex food materials into simpler molecules for absorption by the body. During digestion of food, different parts of the alimentary canal produces different digestive enzymes that helps in digestion of different components of food. For example, saliva produces salivary amylase that digests the starch. Stomach contains gastric glands that produces pepsin that helps in protein digestion. Apart from that, other enzymes such as trypsin, chymotrypsin also helps in protein digestion. |
