Vedclass · Answer

(A) $Prothrombinase$ is a complex enzyme formed during the blood clotting process that converts $prothrombin$ into $thrombin$.It functions as an antiheparin because it neutralizes the anticoagulant effect of $heparin$.$Heparin$ is a naturally occurring anticoagulant produced by the liver and mast cells that prevents the clotting of blood within the intact blood vessels.Since the $Prothrombinase$ enzyme neutralizes $heparin$ to allow the clotting cascade to proceed,the Reason correctly explains why the enzyme acts as an antiheparin.

Assertion: $Prothrombinase$ enzyme acts as an antiheparin.
Reason: $Heparin$ prevents the coagulation of blood in blood vessels.
