Question: 126. Match List I with List II
| List I | List II |
|---|---|
| A. GLUT-4 | I. Hormone |
| B. Insulin | II. Enzyme |
| C. Trypsin | III. Intercellular ground substance |
| D. Collagen | IV. Enables glucose transport into cells |
Choose the correct answer from the options given below:
(1) A-IV, B-I, C-II, D-III
(2) A-I, B-II, C-III, D-IV
(3) A-II, B-III, C-IV, D-I
(4) A-III, B-IV, C-I, D-II
Answer: Option (1)
Explanation:
GLUT-4 is a glucose transporter protein present in adipose tissue and skeletal muscles. It facilitates the transport of glucose into cells, so A matches with IV.
Insulin is a peptide hormone secreted by the \beta-cells of the pancreas.
Therefore, B matches with I.
Trypsin is a digestive protein that catalyzes the breakdown of proteins into smaller peptides.
Hence, it is an enzyme and C matches with II.
Collagen is a fibrous protein found in the extracellular matrix and forms an important component of the intercellular ground substance.
Thus, D matches with III.
Therefore, the correct matching is A-IV, B-I, C-II, D-III.
