Match the columns and find the right option
`{:(,,"Protein","","Function"),(,a,"Collagen",1,"Glucose transport"),(,b,"Trypsin",2,"Hormone"),(,c,"Insulin",3,"Intercellular ground substance"),(,d,"GLUT-4",4,"Enzyme"):}`

Options

A. a-3, b- 4, c-2, d-1
B. a-4, b- 1, c-2, d-3
C. a-2, b- 4, c-1, d-3
D. a-3, b- 4, c-1, d-2

Answer

To solve the matching question, we need to pair each protein with its corresponding function based on our understanding of their roles in biology. Let's go through each protein one by one.

### Step-by-Step Solution:

1. **Identify the Proteins and Functions:**
- Proteins: Collagen, Trypsin, Insulin, GLUT-4
- Functions: Glucose transport, Hormone, Intercellular ground substance, Enzyme

2. **Match Collagen:**
- Collagen is known to be a structural protein found in connective tissues. It serves as the intercellular ground substance.
- **Match:** Collagen (A) → Intercellular ground substance (3)

3. **Match Trypsin:**
- Trypsin is an enzyme that aids in the digestion of proteins in the pancreatic juice.
- **Match:** Trypsin (B) → Enzyme (4)

4. **Match Insulin:**
- Insulin is a hormone produced by the pancreas that regulates blood sugar levels.
- **Match:** Insulin (C) → Hormone (2)

5. **Match GLUT-4:**
- GLUT-4 is a glucose transporter that is regulated by insulin and is primarily found in adipose tissue and muscle. Its function is to facilitate glucose transport.
- **Match:** GLUT-4 (D) → Glucose transport (1)

### Final Matches:
- A → 3 (Collagen → Intercellular ground substance)
- B → 4 (Trypsin → Enzyme)
- C → 2 (Insulin → Hormone)
- D → 1 (GLUT-4 → Glucose transport)

### Conclusion:
The correct matching is:
- A (Collagen) matches with 3 (Intercellular ground substance)
- B (Trypsin) matches with 4 (Enzyme)
- C (Insulin) matches with 2 (Hormone)
- D (GLUT-4) matches with 1 (Glucose transport)

The right option is **Option 1**.
