BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Your stomach, small intestine and pancreas all make digestive enzymes. The pancreas is really the enzyme “powerhouse” of digestion. It produces the most important digestive enzymes, which are those that break down carbohydrates, proteins and fats.

Detailed explanation-2: -At the brush border of the villi of the small intestine are many proteolytic enzymes, including disaccharidases (maltase, sucrace and lactase) and peptidases (especially dipeptidases that break down dipeptides).

Detailed explanation-3: -Enzymes secreted by intestinal glands are lipase, amylase, sucrase, lactase, maltase, aminopeptidase, carboxypeptidase, etc. Q.

Detailed explanation-4: -Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.

Detailed explanation-5: -Like the small intestine, the large intestine churns the food against its mucous lining and also moves it forward through periodic muscle contractions. But this process is much slower in the large intestine-about 24 hours. Digestion also happens here, but not by enzymes as it did in the small intestine.
