Question

Thrombokinase is produced in_______.

• A. Blood Vessels.
• B. Blood Clotting.
• C. Red Blood Cells.
• D. White Blood Cells.

Answer 1

The correct option is B

Blood Clotting.

The correct answer is option B.

Explanation of the correct option:

1. Thrombokinase is an enzyme present in platelets of blood.
2. Thrombokinase is required in blood clotting.
3. Blood clotting is the process by which the loss of blood is prevented at the site of injury and the injured site is healed.
4. When a blood vessel is injured, thrombokinase is released into the bloodstream by blood platelets.
5. Thrombokinase converts prothrombin (inactive form) into thrombin (active form).
6. Thrombin converts into a protein called fibrinogen which forms a mesh-like network at the site of injury and prevents the loss of red blood cells by trapping them.
7. The whole process results in the formation of a blood clot, which remains until the injury is healed.
8. Thrombokinase enzyme is produced in red blood cells.

Explanation of the incorrect options:

Option A:

1. Blood vessels are long tube-like vessels that are present in the animal or human body.
2. Blood vessels help in circulating blood.

Option C:

1. Red blood cells or erythrocytes are the most abundant cells found in the blood.
2. RBCs play a role in transporting oxygen to cells of the body.

Option D: White blood cells:

1. White Blood cells or leukocytes are colorless nucleated cells found in blood
2. WBCs play a role in providing immunity to pathogens such as viruses and bacteria.

Final Answer: thrombokinase is produced in blood clotting.
