NURSING ANM AND GNM

Detailed explanation-1: -Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON ). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-2: -A: All biochemical compounds contain carbon, hydrogen, and oxygen; and proteins as well as nucleic acids contain nitrogen. Phosphorus is the only element that is identified with nucleic acids.

Detailed explanation-3: -Therefore, nitrogen is the element that is only present in proteins but not in lipids or carbohydrates.

Detailed explanation-4: -Phosphorus is an essential component of all cells; the element forms the backbone of nucleic acids, without which cells cannot reproduce. Phosphorus is also incorporated in nucleotides, sugars, proteins, and lipids.

Detailed explanation-5: -Nitrogen is one of the essential constituents of all living organisms. It is present in Nucleic Acids (Nitrogen bases).
