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.

What is difference between prothrombin and thrombin?
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.
Why does the iron present in the blood does not rust?
A substance or complex of substances called prothrombin activator is formed in response to rupture of vessels or damage to the blood itself. The detailed mechanism by which prothrombin activator is formed are still incompletely understood, however, both involves a series of plasma proteins, especially beta- globulins which along with other blood clotting factors like factor IV (calcium)enter into clotting process. 2.Prothrombin activator catalyzes the conversion of prothrombin into thrombin in the presence of calcium. 3.The thrombin acts as an enzyme to convert fibrinogen into fibrin threads that enmesh platelets, blood cells and plasma to form a hard blood clot. Citrates and oxalates which are commonly used as anticoagulants are effective because they remove calcium from the blood by formation of insoluble citrate or oxalate salts of calcium. If calcium is added in excess the clotting power of blood is restored. In formation of oxy-hemoglobin, oxygen does not combine with two positive valences of the ferrous iron in the hemoglobin molecule. Instead, it binds loosely with one of the six "coordination" valences of the iron atom. This is an extremely loose bond so that combination is reversible. Furthermore, the oxygen does not become ionic oxygen but is carried as molecular oxygen to the tissue where it is released into the tissue fluids in the form of dissolved molecular oxygen rather than ionic oxygen. This explains why blood does not rust despite having the all necessary substrates for the formation of the rust
Prothrombin time is a blood test used to evaluate?
Extrinsic clotting factor
What is the difference between inhibitor and activator?
difference between activator and inhibitor
What is the difference between galvanizing and electroplating?
What is the difference between electroplating and galvanising
Prothrombin converts prothrombin to?
Thrombin
What are the correct order of thrombin fibrin thromboplastin prothrombin and fibrinogen inblood clotting mechanism?
Thromboplastin -> Prothrombin -> Thrombin -> Fibrinogen -> Fibrin
How does Heparin prevents blood from clotting?
inhibiting the formation of prothrombin activator and the action of thrombin on fibrinogen

What enzyme is used in blood clotting?
Prothrombinase converts prothrombin into enzyme thrombin.
What is the Sequence blood clotting?
Prothrombin-->Thrombin; Fibrinogen--> Fibrin (activated by thrombin)The sequence of blood clotting is called Coagulation.
What is the ion required in the coagulation process where Prothrombin is converted to thrombin?
sodium
What is used in blood clotting?
Prothrombinase converts prothrombin into enzyme thrombin.
Does heparin prevent blood from clotting?
inhibiting the formation of prothrombin activator and the action of thrombin on fibrinogen
What is the definition of thrombokinesse?
an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
What is the function of thromboplastin in homeostasis?
In the final step of blood clotting cascade, Thromboplastin activates the prothrombin to Thrombin. Then the activated thrombin helps in the conversion of Fibrionogen into Fibrin (Mesh like fibrils which forms the clot).
Formation of a blood clot?
Platelets rupture, releasing thromboplatin Ca++ Prothrombin converted to thrombin fibrinogin converted to fibrin fibrin thread network, clot.
