describe in detail the importane of digestive juicies in digestive system . highlight the role of pancreatic juice
Dear student
Please refer the solution below for the said query
Pancreatic juice contains proteases, lipase, nucleases, amylase, water, mucus and sodium bicarbonate. Proteases are enzymes that digest proteins, lipases digest lipid or fat, nucleases digest nucleic acids and amylases digest starch. Mucus lubricates and water dilutes the food substances. Sodium bicarbonate increases pH for optimum enzyme functions.
Hope this information clears your doubt about the topic.

Following are the glands associated with the digestive system and their secretions:
ORGAN | GLAND | SECRETION | ENZYMES | ACTION OF ENZYME |
Mouth | Salivary gland | Saliva | Salivary amylase | Breaks down starch to sugar |
Stomach | Gastric glands | Gastric juices | 1. Pepsin 2. HCl 3. Mucus | 1.Breaks down protein-peptones 2. Kills-germs, create acidic medium. 3. Protect the walls of stomach from the action of HCl |
duodenum | 1. Liver 2. Pancreas | 1. Bile juice 2. Pancreatic juices | _ 1. Amylopsin 2. Trypsin 3. Lipase | Emulsification of fats, create alkaline medium 1. Breaks down starch to maltose 2. Breaks down protein to amino acid 3. Breaks down emulsified fats |
Small intestine (site of complete digestion) | Intestinal glands | Intestinal juices (recives bile & pancreatic juice | 1. Erepsin 2. Maltase | CONVERTS: Protein--amino acid Sugar—glucose |
