The major role of minor elements inside living organisms is to act as?
Correct answer: A. Cofactors of enzymes
- A. Cofactors of enzymes
- B. Building blocks of important amino acids
- C. Constituent of hormones
- D. Binder of cell structure
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.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
