The basic framework structure of all types of membranes is:
Correct answer: C. Phospholipids
- A. Glycoproteins
- B. Glycolipids
- C. Phospholipids
- D. All of these
Explanation
The correct answer is phospholipids. These molecules form a bilayer that serves as the fundamental structure of cell membranes, providing a semipermeable barrier between the cell and its environment. Glycoproteins and glycolipids are important for cell recognition and signalling but do not form the basic structural framework of membranes. The option 'All of these' is incorrect because only phospholipids form the core structural framework, despite the presence of other molecules in the membrane.

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.
