Vitamin K is required for A. Carboxylation B. Hydroxylation C. Oxidation D. Reduction
Within the cell vit.k undergo reduction by enzyme vit.k epoxide reductase and vit.k convert into vit.k hydroquinon which are active form then the enzyme gamma glutamyl carboxylase act which oxidise the vit.k hydroquinon and carboxylation of glutamate in clotting factor, it is a post transcriptional modifications.
