Question

How many carbohydrate digesting enzymes in the list given are found in the intestinal juice?
Enterokinase, Chymotrypsin, Aminopeptidase, Pepsin, Lactase, Rennin, Carboxypeptidase, Nuclease, Nucleosidase, Maltase, Sucrase
A. Six
B. Three
C. Five
D. Four

Answer 1

Hint: The breakdown of complex carbohydrates into monosaccharides is known as carbohydrate digestion. The digestion of carbohydrate occurs in the buccal cavity, stomach and the intestine. Carbohydrate digestion is helped by the secretions of the salivary glands, pancreas, gastric glands, and intestinal glands. The complete process of carbohydrate digestion is enzymatic and catabolic.

Complete answer:
Option: A – Since only three carbohydrate digesting enzymes are present in the list.
So, this option is not correct.
Option: B – There are three carbohydrate digesting enzymes present and also on factual data they are found in the intestinal juice.
Therefore, this option is correct.
Also, Maltase digests Maltose into Glucose. Lactase digests Lactose into Glucose and Galactose. Sucrase, also called Invertase, digests Sucrose into Glucose and Fructose. Furthermore, all of these three enzymes are present in the intestinal juice derived partly from the pancreatic juice and partly from the intestinal glands.
Option: C and D are also incorrect because only three carbohydrate digesting enzymes are present in the provided list not five or four.

Hence, Option B Three is the correct answer.

Note:
The mechanical action of chewing and the chemical action of salivary amylase start carbohydrate digestion in the mouth. Carbohydrates are chemically broken down in the small intestine rather than the stomach. The chemical breakdown of digestible carbohydrates to monosaccharides is completed by pancreatic amylase and disaccharidases. Later the monosaccharides are absorbed through the bloodstream and transported to the liver.
