The best way to determine experimentally, for the 2018 revision of the DRI, the
EAR for VIT K in a small subset of the population would be:
a. in a clinical research ward, give subjects an antibiotic and graded levels of VIT K
and measure blood clotting rates

allows carbon dioxide to be fixed to glutamic acid, forming gamma-
carboxyglutamic acid residues
c. perform a balance trial by measuring the VIT K content in diet, urine and feces.
d. tell groups of subjects to eat diets with different levels of VIT K and measure the
incidence of bone fractures. - Correct Answer-a
