Question

All biomolecules (macromolecules) in the cell are ___ based.

1) Protein
2) Carbohydrate
3) Lipid
4) Nucleic Acid

Answer 1

All biomolecules in the cell are carbon based, including proteins, carbohydrates, lipids, and nucleic acids. Carbon's unique bonding properties make it the backbone of these essential biological macromolecules.

Step-by-step explanation:

All biomolecules (macromolecules) in the cell are carbon based. The four main types of macromolecules found in living organisms are:

1. Proteins.
2. Carbohydrates.
3. Lipids.
4. Nucleic Acids.

Cells are composed of these complex molecules which are a subset of organic molecules. Each of these biological macromolecules is a vital component of the cell and performs a wide variety of functions. The fundamental element for all these macromolecules is carbon, due to its unique properties that allow it to form versatile covalent bonds, making it ideal to serve as the backbone of macromolecules.
