BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Pancreatic juice is usually colourless, odourless and alkaline, tasting strongly of sodium bicarbonate, with a pH ranging from 8.0 to 8.3. Its specific gravity ranges from 1.007 to 1.042 and varies directly with the protein content.

Detailed explanation-2: -Sodium bicarbonate is responsible for the slight alkalinity of pancreatic juice (pH 7.1 to 8.2), which serves to buffer the acidic gastric juice in chyme, inactivate pepsin from the stomach, and create an optimal environment for the activity of pH-sensitive digestive enzymes in the small intestine.

Detailed explanation-3: -The pancreatic juice It is a clear liquid secreted by the pancreas composed mainly of water, electrolytes, and enzymes. The pancreas plays an important role in the digestion of food and it is the enzymes found in pancreatic juice that allow the body to break down carbohydrates, proteins, and fats.

Detailed explanation-4: -Secretin stimulates the secretion of bicarbonate-rich pancreatic fluid. [11] Secretin enters the intestinal lumen and stimulates bicarbonate secretion, ultimately neutralizing gastric H+, which plays an essential role in fat digestion by creating a more neutral (pH 6 to 8) environment.

Detailed explanation-5: -The pancreas also secretes large amounts of sodium bicarbonate, which protects the duodenum by neutralizing the acid that comes from the stomach Stomach The stomach is a large, bean-shaped, hollow muscular organ consisting of four regions: Cardia Fundus Body Antrum read more .
