Question
What precipitates the conversion of fibrinogen after an injury?Multiple choice question.The release of prothrombinThe release of thrombinThe release of fibrin
Solution
The conversion of fibrinogen after an injury is precipitated by the release of thrombin. Thrombin is a key enzyme in the coagulation cascade, which is activated when there is an injury to the body. It acts on fibrinogen, a soluble protein present in the blood, converting it into fibrin. Fibrin then forms a mesh-like structure that forms the basis of a blood clot, effectively sealing off the injury and preventing further blood loss. Therefore, the correct answer to your multiple choice question is "The release of thrombin".
