The major role of minor elements inside living organisms is to act as?

Explanation

Minor elements are those which are required in the quantity of less than milligram/gram of dry matter, but they are essential for proper growth and development of an organism e.g., Cl, Mn, B, Zn, Cu, Mo, etc. These elements work as non­protein cofactor in enzymes e.g., Zn, Cu, etc. They also take part in oxidation-reduction reactions, e.g., Cu, with variable valency. Chloride ion enhances the activity of salivary amylase. Zinc is required for the activity of carbonic anhydrase and alcohol dehydrogenase, etc.
