Question 3 of 5
What enzyme cleaves plasminogen to form active plasmin?
Correct Answer: A
Rationale: Plasminogen is cleaved by the enzyme plasmin to form active plasmin. Plasminogen is the inactive precursor of plasmin, which is responsible for breaking down fibrin clots. Fibrinogen is a protein involved in blood clotting but does not cleave plasminogen to form plasmin. Thrombin is also involved in blood clotting but does not directly cleave plasminogen. Streptokinase is a bacterial enzyme that can activate plasminogen, but it does so indirectly by forming a complex with plasminogen.
