Identify the correct pair.
(A) Zinc essential for tissue repair
(B) Cobalt essential for formation of leucocytes
(C) Iodine synthesis of thyroid hormones
(D) Manganese synthesis of insulin
Zinc is required for producing enzymes. It produces 300 enzymes in the body and it plays key roles in DNA synthesis, cell division, and protein synthesis; all necessary for tissue regeneration and repair. Cobalt is an important element in the formation of cobalamin or vitamin B12 and not in the formation of leucocytes. Thyroxine (Thyroid hormones) is produced by attaching iodine atoms to the ring structures of tyrosine molecules. Manganese is part of many enzymes, however, it is not involved in the synthesis of Insulin. Therefore option B is correct.
