WebThree steps are involved in common pathway activation: Prothrombinase is generated on the surface of activated platelets, endothelial cells, and tissue cells. Prothrombinase is a complex of an enzyme, factor Xa, and a cofactor, factor Va, on a procoagulant phospholipid surface. Prothrombinase cleaves prothrombin to thrombin. WebThe blood platelets are the smallest cells of the blood, averaging about 2 to 4 μm in diameter. Although much more numerous (150,000 to 400,000 per cubic millimetre) than the white cells, they occupy a much smaller fraction of the volume of the blood because of their relatively minute size.
