"Carbon-water" molecules, which include valuable sugar as body fuel:
Correct answer: D. Carbohydrates
- A. Nucleic acids
- B. Actin filaments
- C. Lipids
- D. Carbohydrates
Explanation
Carbohydrates are the correct answer because they are often referred to as 'carbon-water' molecules due to their chemical composition. They are made up of carbon, hydrogen, and oxygen, often in the ratio of Cn(H2O)n, which makes them an immediate source of energy in the form of sugars. Nucleic acids, actin filaments, and lipids serve different roles in the body and are not primarily used as immediate energy sources like carbohydrates.

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.
