Question

Name of an enzyme used to dissolve the blood clot is
(A) Streptokinase
(B) Amylases
(C) Invertase
(D) Phenylketonuria

Answer 1

The blood clot formations help to prevent bleeding of blood after an injury. Blood clotting occurs naturally in our body and our body itself dissolves the clot after the injury is healed. But if the clot formed is inside the blood vessels without an injury it will not be dissolved naturally.

Complete step by step answer:
Blood clotting is also called coagulation.
When a cut or injury occurs in our body, blood gets clotted naturally. That is the free-flowing blood changes into a gel form and thus thereby preventing blood loss in our body.
The blood clotting occurs naturally in our body and our body itself dissolves the clot after the injury is healed.
But sometimes if the clot formation is inside blood vessels, it cannot dissolve naturally.
A bacteria present in the human body known as Streptococcus will produce an enzyme known as Streptokinase.
This enzyme acts as a clot buster.
Streptokinase has a fibrinolytic action.
This enzyme breaks down the clots and helps to dissolve the clot.
Streptokinase is given to patients who showed symptoms of a heart attack. It is used to dissolve clots formed in the lungs and legs.
Therefore the answer is an option (A) Streptokinase.

Additional Information
Streptokinase is the enzyme used to dissolve blood clots.
Amylase is an enzyme secreted by the pancreas and salivary glands. It helps in the initial process of digestion.
Invertase is an enzyme derived from yeast. It is used in candy making industries.
Phenylketonuria is a genetic disorder that causes the phenylalanine to produce in our body.
It is caused by a gene defect that helps to create the enzyme needed to break down phenylalanine.

Note:
Streptokinase dissolves the blood clot inside the blood vessels. There are different types of clot-buster but the medication should be done based on the type of clot and where the clot is formed. Certain drugs such as blood thinners will not dissolve clots but prevent them from growing larger.
