Question

Match the following blood proteins with their appropriate functions:

$\begin{array}{cc}\text{Proteins}& \text{Functions}\\ \text{1. Globulins}& \text{i) osmotic balance of blood}\\ \text{2. Albumins}& \text{ii) oxygen transport in the blood}\\ \text{3. Haemoglobin}& \text{iii) clotting of blood}\\ \text{4. Fibrinogen}& \text{iv) defense mechanism of body}\end{array}$

• A. 1 - ii; 2 - i; 3 - iv; 4 - iii
• B. 1 - iv; 2 - i; 3 - ii; 4 - iii
• C. 1 - iii; 2 - ii; 3 - iv; 4 - i
• D. 1 - iv; 2 - iii; 3 - ii; 4 - i

Answer 1

The correct option is B 1 - iv; 2 - i; 3 - ii; 4 - iii

Blood is made up of various types of proteins. Three major proteins found in blood plasma are - albumins, globulins and fibrinogen.

Albumins are proteins which help in maintaining the osmotic balance of blood.

Globulins are primarily involved in defense mechanisms of the body. Globulins like antibodies bind to foreign organisms which might have entered into the blood from outside and destroy them.

Fibrinogens are the proteins which initiate the blood clotting process, thereby preventing loss of blood from the body.

Haemoglobin is responsible for the transportation of oxygen in the blood. It is also involved in the transportation of carbon dioxide.

Thus, the correct match for these proteins will be:

$\begin{array}{cc}\text{Proteins}& \text{Functions}\\ \text{1. Globulins}& \text{defense mechanism of body}\\ \text{2. Albumins}& \text{osmotic balance of blood}\\ \text{3. Haemoglobin}& \text{oxygen transport in the blood}\\ \text{4. Fibrinogen}& \text{clotting of blood}\end{array}$
