Question

The enzyme TPA is used to .....
A. Maintain turgor pressure
B. Strengthen tissue
C. Increase plasma
D. Dissolve blood clot

Answer 1

Hint: TPA stands for tissue plasminogen activator, it is a clot Dissolving enzyme

Complete answer: It is naturally produced by the endothelial cells( those types of cells which present on the line of blood vessels) and undergoes the process of fibrinolysis that is breaking of a blood clot.
2. TPA is an enzyme so it accelerates the process of conversion of plasminogen into the plasmin.
3. It is naturally present in our body but also manufactured artificially by different biotechnological companies.
4. Artificially it is manufactured by the recombinant DNA technology and they form recombinant tissue plasminogen activator.
5. The major function of the tPA is to dissolve the blood clots and convert them into the plasmin.
6. TPA is a proteolytic enzyme found in blood and tissue.
7. As it converts the plasminogen into plasmin, plasmin is involved in a variety of biological processes., including the cell growth and tumor, migration, inflammation. Its primary function is to lysis of fibrin in the vasculature.
8. So from the above discussion, we can conclude that the TPA is a major part of removing clots from the blood vessels.

So the correct answer is Option D. Dissolve blood clot

Note: TPA is provided externally in case of blockage in blood vessels. When the coronary arteries have a blockage and the flow of blood to the heart muscle is sustained and the situation of myocardial infarction happens then for the emergency treatment we can give tPA which dissolve the blood clots and the flow of blood can regain.
