Question

Identify the incorrect match between protein and its role.

• A. Keratin - Structural component of hair
• B. Immunoglobins - Protection of body against diseases
• C. Haemoglobin - Transport of oxygen in muscles
• D. Thrombin - Blood clotting

Answer 1

The correct option is C Haemoglobin - Transport of oxygen in muscles

Keratin is the structural component of the hair.

Immunoglobins are the proteins which are involved in the protection

Transport of oxygen in muscles takes place by myoglobin. Haemoglobin is the respiratory pigment present in the blood. The haemoglobin present in the RBC combine with oxygen to form oxyhaemoglobin and transports the oxygen to different part of the tissue. On reaching the tissues the bond between the oxygen and haemoglobin breaks and it releases oxygen.

Thrombin is a protein which helps in the clotting of proteins.

So, the correct answer is option C.
