Question

Quizplus · Accepted Answer

Vitamin K is essential for the activation of clotting factors II, VII, IX, and X which are responsible for proper blood clotting. Without sufficient levels of vitamin K, blood would not clot efficiently, leading to potential bleeding disorders such as hemophilia. Vitamin K does not directly activate fibrinogen or stabilize fibrin polymer, nor does it activate antithrombin III.
