Lipids as hydrophobic compounds are component of:
Correct answer: D. Cellular membrane
- A. Genetic material
- B. Cell wall
- C. Cytoplasm
- D. Cellular membrane
Explanation
The correct answer is Option D: Cellular membrane. Lipids, particularly phospholipids, are integral to the structure of cellular membranes. They form a bilayer that constitutes the basic framework, ensuring membrane fluidity and selective permeability. The other options are incorrect because lipids do not constitute genetic material, are not primary components of the cell wall, and while present in the cytoplasm, do not define it.

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.
