Quizplus · Accepted Answer

The active form of vitamin K is a cofactor in the reaction that carboxylates glutamic acid residues to form delta-carboxyglutamic acid residues on clotting factors II, VII, IX, etc.This carboxylation step is necessary for these factors to function normally.Once formed, the delta-carboxyglutamic acid residues permit binding of the coagulation protein to calcium, which initiates the ionic bridge formation through binding with phospholipids.
