One important biotechnology advance is the mass production of the enzyme tissue plasminogen activator (TPA).You would expect people with low TPA to have difficulty _______ due to _______.
A) breaking down clots; a deficiency of plasminogen
B) breaking down clots; a deficiency of plasmin
C) breaking down clots; an excess of plasmin
D) forming clots; a deficiency of plasminogen
E) forming clots; an excess of plasmin

Question

Quizplus · Accepted Answer

Tissue plasminogen activator (TPA) is an enzyme that helps to break down blood clots by converting plasminogen to plasmin, which is responsible for dissolving fibrin clots. Thus, people with low levels of TPA would have difficulty breaking down clots due to a deficiency of plasmin. The other answer choices are incorrect as they relate to either breaking down clots with excess plasmin or forming clots with a deficiency or excess of plasminogen.
