Quizplus · Accepted Answer

The criterion of adequacy used to determine the EAR and RDA for copper is normal levels of copper and a protein used to transport copper, called ceruloplasmin. This reflects the important role of copper in a wide range of physiological functions, including iron metabolism, connective tissue synthesis, and neurotransmitter synthesis.
