Question

A child took sugarcane and sucked its juice, regarding which of the following matches is correct?
(A) Substrate- Proteins, Enzyme-pepsin, site of recreation Duodenum, salivary glands, products formed- polypeptides of Glucose
(B) Substrate-Starch, Enzyme-Amylase, site of secretion- salivary glands, products formed- Glucose.
(C) Substrate-Lipids, Enzyme- lipase, site of creation – pancreas globules, products formed – fat.
(D) Substrate-Sucrose, Enzyme- invertase, Site of Secretion-Duodenum, products formed- Glucose, and fructose.

Answer 1

Hint: The process which involves the hydrolysis of large and complex organic molecules is called digestion. Foodstuffs into smaller and water-soluble molecules. and that can be easily absorbed by the gastrointestinal tract for utilization by the organism. Digestion of the macromolecules also promotes the absorption of fat-soluble vitamins and certain minerals.
Cooking of the food, and muscles significantly improve digestion.

Complete answer:
(A) Substrate- Proteins, Enzyme-pepsin, site of recreation Duodenum, salivary glands, products formed- polypeptides of Glucose: Most protein digestion occurs in the small intestine, by the proteolytic enzymes of the pancreas and intestinal mucosa. Major proteases present in pancreatic enzymes are trypsin, chymotrypsin, carboxypolypeptidase, and proelastase.
(B) Substrate-starch, Enzyme-Amylase, site of recreation salivary glands, products formed- Glucose: Pancreatic secretion, like saliva, contains a large quantity of an alpha-amylase called pancreatic amylase. Pancreatic amylase hydrolyzes starch into the maltose, maltotriose, and alpha- limit dextrins.
(C) Substrate-Lipids, Enzyme- lipase, site of creation – pancreas globules, products formed – fat.
Lipid digestion occurs in the stomach through enzymes, most occurs in the small intestine through the action of pancreatic occurs.
(D) Substrate-Sucrose, Enzyme- invertase, Site of Secretion-Duodenum, products formed- Glucose, and fructose: The resultant products are disaccharides. The final digestion of di- and igo- saccharides to monosaccharides primarily occurs at the mucosal lining of the upper jejunum. This is carried out by oligosaccharides and disaccharides. The enzyme sucrose is capable of hydrolyzing a large quantity of table sugar. In contrast, lactase is the rate-limiting and consequently, the use of milk sugar is limited in humans.
$Sucrose\mathop \to \limits^{Sucrase} Glu\cos e + Fructose$
Sucrase catalyzes the hydrolysis of alpha1- 2beta glycosidic bonds of disaccharide sucrose into glucose and fructose.

So the correct option is option D.

Note: Sucrose is an important source of dietary carbohydrates. It is sweeter than the common sugar. namely glucose, maltose, and lactose. Sucrose is employed as the sweetening agent in the food industry. A disaccharide consists of two mano- saccharide units held together by glycosidic bond. They are crystalline in the state, water-soluble, and sweet to taste.
