Identify the function of each of the enzyme given below. Also write the sources of each of these enzymes. (i) Trypsin (ii) Maltase (iii) Pepsin |
|
Answer» (i) Trypsin: Trypsin is a proteolytic enzyme which converts peptones into dipeptides. in small intestine. Pancreatic juice contains inactive trypsinogen. Trypsinogen is activated by enzyme enterokinase into trypsin, which further activates the other enzyme of intestinal juice. (ii) Maltase: It converts maltose to glucose. It is present in succus entericus. Secretion from brush border cells of mucosa and goblet cells contain enzyme succus entericus, containing variety of enzymes to complete the process of digestion. (iii) Prepsin: Pepsin is a proteolytic enzyme that which converts proteins to peptones. Gastric cells are the source of Pepsin. Mucosa of stomach have gastric glands having three types of cells : Mucus neck cells that secrete mucus, peptic or chief cells that secretes proenzyme pepsinogen and parietal or oxyntic cells that secretes HCI. HCI activates the prepsinogen to pepsin to digest protein. |
