There is a long chain reaction from the moment one recieves a cut to the final stage where the cut is healed. The process involves many chemical reactions. In order for the blood to produce a final clot that will stem the bleeding, the blood turns a protein called PROTHROMBIN into THROMBIN. Thrombin is an enzyme that presides over the conversion of a substance called fibrinogen to fibrin, which promotes blood clotting.

Prothrombin is an inactive precursor protein produced in the liver, while thrombin is an active enzyme involved in blood clotting. When prothrombin is cleaved by an enzyme called thrombin during the clotting process, it is converted into thrombin. Thrombin then plays a crucial role in converting fibrinogen to fibrin, initiating blood clot formation.
The cascade of reactions involving thrombin, which is activated from prothrombin, leads to the conversion of fibrinogen to fibrin. This process involves the cleavage of fibrinogen to form fibrin monomers, which then polymerize to form a fibrin clot. This clotting cascade is a crucial step in the formation of a stable blood clot.
Common methods used to measure coagulation include the prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalized ratio (INR), and thrombin time (TT). These tests help assess the clotting function of the blood and are useful in monitoring patients on anticoagulant therapy or those with bleeding disorders.
The correct color tube for a thrombin test is typically a light blue tube. This tube contains sodium citrate as an anticoagulant, which is needed for coagulation studies.
Removal of calcium ions from a blood sample would impair the clotting cascade as calcium is necessary for the conversion of prothrombin to thrombin, which is a crucial step in blood clotting. Without sufficient calcium, the blood would have difficulty forming a stable clot, which could result in prolonged bleeding or difficulty stopping bleeding when an injury occurs.
Prothrombin is converted to thrombin by the enzyme thromboplastin. Thrombin plays a vital role in the clotting cascade by converting fibrinogen into fibrin, which forms a mesh that helps stop bleeding.

inhibiting the formation of prothrombin activator and the action of thrombin on fibrinogen
Prothrombinase converts prothrombin into enzyme thrombin.
Prothrombin-->Thrombin; Fibrinogen--> Fibrin (activated by thrombin)The sequence of blood clotting is called Coagulation.

Prothrombinase converts prothrombin into enzyme thrombin.
The liver is responsible for producing prothrombin, which is a precursor to the blood-clotting protein thrombin. Thrombin plays a crucial role in the blood coagulation process by converting fibrinogen into fibrin to form clots and prevent excessive bleeding.

an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
Prothrombin is a soluble protein found in blood plasma. It plays a key role in the blood clotting process by being converted into thrombin, which helps form a blood clot.
