Question

Quizplus · Accepted Answer

Tissue plasminogen activator (tPA) is the protein responsible for helping break down clots after they are no longer needed. It converts plasminogen to plasmin, which breaks down fibrin, the protein that forms the basis of clots. Choice A (albumin) is a protein involved in regulation of blood volume and pressure, but not clotting. Choice C (prothrombin activator) is an enzyme that initiates the coagulation cascade and promotes clot formation. Choice D (hemoglobin) is a protein that binds and transports oxygen in the blood, but has no role in clotting.
