What substance triggers the formation of fibrin from fibrinogen?
A) Collagen
B) Calcium ions
C) Prothrombin
D) Thrombin

Asked by jnorton1024

Answer (2)

Thrombin is the enzyme that triggers the formation of fibrin from fibrinogen in the blood clotting process. It converts fibrinogen, a soluble protein, into fibrin, which then forms a stable blood clot. Calcium ions assist in this process but do not directly perform the conversion.

Thrombin is the enzyme that triggers the formation of fibrin from fibrinogen during blood coagulation. Calcium ions assist thrombin in this process, but they do not directly convert fibrinogen to fibrin. Other factors like collagen are involved in the clotting response but do not trigger this specific reaction. ;
