Question

Match the following. Identify the correct match between Set-I and Set-II

SET-I	SET-II
A. INSULIN	I. STOMACH
B. PEPSINOGEN	II. SALIVARY GLAND
C. BILIRUBIN	III. LIVER
D. PTYALIN	IV. INTESTINE
	V. PANCREAS

(a) A-V, B-I, C-III, D-II
(b) A-II, B-IV, C-I, D-V
(c) A-IV, B-III, C-I, D-II
(d) A-V, B-II, CI, D-IV

Answer 1

Hint: The enzymes and hormones are secreted by exocrine and endocrine glands. They are specific to a particular substrate. The enzymes help in carrying out a biological process whereas the hormones help in regulation of the physiological processes.

Complete answer:
To solve this question, we must discuss the options of set A.

Insulin – It is a hormone produced by the islet of langerhans cells present in the pancreas. This hormone is responsible for lowering the glucose level in the blood. The correct match is V-pancreas.

Pepsinogen- It is a digestive enzyme present in the stomach. It is present in the gastric juice which helps in lysis of proteins. The correct match is I-Stomach.

Bilirubin- It is a water insoluble pigment formed by the breakdown of heme. It is excreted by the liver. The correct match is III-Liver.

Ptyalin- It is an enzyme present in saliva secreted by the salivary gland. It breaks down starch to dextrin and maltose. The correct match is II-salivary gland

Hence, the correct answer is option (a).

Note: The enzymes are the catalyst which speeds up the rate of reaction. It converts the suitable substrate into different molecules called the product. In our body all the physiological reactions are carried up in the presence of enzymes. These enzymes require an adequate temperature, pH, substrate concentration to carry out its function.
