Answer to Question 1
Vitamin K functions as a coenzyme in a variety of reactions that ultimately constitute the life-or-death process by which blood clots form. For your blood to coagulate and form a clot, a cascade of chemical reactions must first take place. After a cut or scrape occurs, various clotting factors are activated by vitamin K, allowing the next reactions in the cascade to take place. These reactions ultimately result in the production of fibrin, a protein that forms a web-like clot that stops the bleeding.
