Question

The element present in trace in insulin is:
A. Iron
B. Cobalt
C. Zinc
D. Magnesium

Answer 1

Hint: To determine the answer to this question we should know about trace elements and insulin. Trace elements are the element whose minute quantity is required for the proper growth of the body. Fourteen elements are the trace elements. Insulin is the hormone formed by the protein molecules. Insulin is formed by the beta cells of the pancreatic islands.

Complete answer:Insulin is responsible for the metabolism of protein, carbohydrate, and fat. The excess concentration of blood glucose causes diabetic Mellitus which results due to the dysfunction of insulin. The dysfunction of insulin affects the trace elements. Zinc is one of the essential micronutrients.Zinc is present in all cells and it is essential for the immune system of the body.Zinc is an oxidant. It is important for insulin synthesis, storage, and metabolism. Zinc initiates and promotes insulin resistance. So, it improves glucose tolerance by increasing the pancreatic insulin content.Insulin is secreted in the form of zinc crystals. Zinc is required to maintain the structural integrity of the insulin. It works as a cofactor for the enzyme which is related to glucose metabolism.
So, the element present in the trace in insulin is zinc.

Therefore, option (C) zinc, is correct.

Note:The fourteen trace elements are cobalt, zinc, copper, rubidium, molybdenum, vanadium, iron, selenium, manganese, lead, arsenic, vanadium, cadmium, and chromium. Other elements like chromium, vanadium, manganese, molybdenum, and selenium also trace elements that affect insulin function. All of these elements enhance insulin action. These elements activate the insulin receptor sites.
