The most abundant lipid in cell membrane is
Correct answer: A. Phospholipid
- A. Phospholipid
- B. Cholesterol
- C. Steroid
- D. Waxes
Explanation
The correct answer is phospholipids. They are the most abundant lipids in cell membranes and are essential for forming the lipid bilayer, which is the fundamental structure of cell membranes. Phospholipids have unique properties, with hydrophilic heads and hydrophobic tails, allowing them to form bilayers in aqueous environments. Cholesterol, while crucial for membrane fluidity and integrity, is present in smaller amounts compared to phospholipids. Steroids and waxes do not form the structural basis of cell membranes, with steroids serving more as signaling molecules and waxes not being involved in cell membrane structure.

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.
