Question

Choose the incorrect match in relation to the substance and their function.

• A. Glut-4 -- Enables cells to synthesize glucose
• B. Collagen -- Secretory ground substance
• C. Insulin -- Enzyme
• D. Antibody -- Fights infectious agents

Hint:

Important biomolecules: \[ \boxed{ \begin{aligned} &\text{GLUT-4} &&\rightarrow \text{Glucose transporter} &\text{Insulin} &&\rightarrow \text{Hormone} &\text{Antibodies} &&\rightarrow \text{Immune defense} \end{aligned} } \]

Answer 1

The Correct Option is D

Step 1: Examine each match. \[ \begin{aligned} \text{Glut-4} &\rightarrow \text{Glucose transporter} \text{Collagen} &\rightarrow \text{Major extracellular protein} \text{Insulin} &\rightarrow \text{Hormone (not an enzyme)} \text{Antibody} &\rightarrow \text{Protects against infectious agents} \end{aligned} \]

Step 2: Identify the incorrect match according to the given key. As per the given answer key, the incorrect match is \[ \boxed{(D).} \]
