Question

which three (3) elements are involved in the structure of all four biomolecules? (select all that apply)

oxygen (o)

phosphorus (p)

nitrogen (n)

carbon (c)

hydrogen (h)

rewatch

Explanation:

Biomolecules include carbohydrates, lipids, proteins, and nucleic acids. All four types of biomolecules contain carbon (C), hydrogen (H), and oxygen (O). Proteins and nucleic acids also contain nitrogen (N), and nucleic acids and some lipids (like phospholipids) contain phosphorus (P). But the question asks for elements in all four biomolecules.

Answer:

oxygen (O), carbon (C), hydrogen (H)
