Question

All biomolecules are made up of the elements.
1. carbon, hydrogen, and oxygen.
2. carbon, hydrogen, nitrogen, and oxygen.
3. carbon, hydrogen, nitroen, and sulfur.
4. carbon, hydrogen, oxygen, and sulfur.

Answer 1

All biomolecules are primarily made up of the elements mentioned in option 2: carbon, hydrogen, nitrogen, and oxygen. These four elements are the fundamental building blocks of proteins, nucleic acids, carbohydrates, and lipids, which are the main categories of biomolecules. While other elements such as sulfur and phosphorus may also be present in certain biomolecules, the core elements common to all biomolecules are indeed carbon, hydrogen, nitrogen, and oxygen.
