The human pancreas secretes pancreatic juices. Match the pairs of enzymes and its function present in it.
Enzyme | Function |
---|---|
Amylase | Digestion of fat |
Trypsin | Digestion of protein |
Lipase | Digestion of starch |
A. 1-c, 2-a, 3-b
B. 1-c, 2-b, 3-a
C. 1-b, 2-c, 3-a
D. 1-a, 2-b, 3-c
Solution
Amylase is an enzyme that breaks down amylose which is a form of starch. Trypsin is a pancreatic enzyme that functions mainly by breaking down proteins into amino acids. Lipase is an enzyme that breaks down lipids.
Complete answer: Enzymes are catalysts, which serve mainly to increase the rate of various reactions. All biological functions are enzyme guided and thus, enzymes are extremely crucial for the metabolic functioning in living organisms. Enzymes are commonly named after their function such as maltase is an enzyme that breaks down maltose, lipoxygenase is an enzyme that oxygenates a lipid molecule. Phospholipase is an enzyme that removes a phosphate group from a lipid. Thus, the function of an enzyme can be easily ascertained from the name. Most enzymes have the name ending with -ase or -in. A major portion of all enzymes have an ending with -ase, whereas, there are enzymes associated with protein that have a name ending with -in, such as trypsin, pepsin, rennin, etc. Amylose is a starch molecule found in many plant sources as amylose or amylopectin and is digested by amylase. Trypsin is a pancreatic enzyme that digests proteins and lipase is an enzyme that digests lipids.
Thus, option B is the correct answer.
Note: The name of the enzyme always denotes the substrate of the enzyme, acetylase, pectinase, maltase. Pancrelipase is a commercially available medication for digestive disorders that consists of a mixture of amylase, trypsin and lipase.
