Carbon is involved in the synthesis of various complicated cellular structures because of its ability to make
Correct answer: C. Four covalent bonds
- A. Two ionic bonds
- B. Four ionic bonds
- C. Four covalent bonds
- D. Two hydrogen bonds
Explanation
Carbon is unique in its ability to form four covalent bonds, allowing it to be the backbone of complex organic molecules. This tetravalency enables carbon to bond with other carbon atoms and various elements, forming long chains and intricate structures found in biological macromolecules. Options A and B describe ionic bonds, which are not typical for carbon. Option D describes hydrogen bonds, which are intermolecular forces rather than bonds formed by carbon itself.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
