Which of the following is primarily responsible for neutralizing the extrinsic tenase complex?

Question

Quizplus · Accepted Answer

Tissue factor pathway inhibitor (TFPI) is primarily responsible for neutralizing the extrinsic tenase complex. It inhibits the activity of factor VIIa and factor Xa, which are key components of the extrinsic tenase complex. TFPI acts as a feedback inhibitor to regulate the coagulation cascade and prevent excessive clotting. SERPINs (B) are a class of protease inhibitors that inhibit a broad range of proteases, including some involved in coagulation. Proteins C and S (C) are involved in the regulation of the intrinsic tenase complex and have a limited role in the regulation of the extrinsic tenase complex. APS (D) stands for antiphospholipid syndrome, which is a disorder caused by antibodies that target phospholipids, leading to an increased risk of clotting. APS is not a molecule responsible for neutralizing the extrinsic tenase complex.
