Which one is the basic element found in all organic compounds?
Correct answer: B. Carbon
- A. Oxygen
- B. Carbon
- C. Hydrogen
- D. All of these
Explanation
Carbon is the fundamental element found in all organic compounds. Its ability to form four covalent bonds allows for the creation of complex and diverse organic molecules. Unlike carbon, oxygen and hydrogen, although crucial to life, do not define organic compounds. Oxygen is involved in respiration, and hydrogen is abundant and significant in forming compounds, but neither is the basic element of organic compounds. Therefore, option B, carbon, is the correct answer.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
