Verified step by step guidance1
Begin by understanding what biomolecules are. Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.
Recognize that biomolecules are primarily composed of elements that can form stable covalent bonds, allowing for complex structures necessary for biological functions.
Identify the most common elements found in all biomolecules. These elements are carbon (C), hydrogen (H), and oxygen (O). They form the backbone of biomolecules, providing structure and function.
Consider the role of each element: Carbon is the central element in organic chemistry, forming chains and rings. Hydrogen is involved in forming bonds and maintaining structure. Oxygen is crucial for energy production and structural integrity.
Review the options provided and select the set of elements that are universally present in all biomolecules: Carbon, Hydrogen, and Oxygen.
