  1. AAn improved model of the structure of cell organelle as proposed by Singer (1972) widely accepted as a fluid m
  2. BIt is mainly composed of lipids and proteins
  3. CIt is mainly composed of lipids and carbohydrates.
  4. DDepending on the number of side chains, membrane proteins can be classified as integral and peripheral.

Correct answer

B. It is mainly composed of lipids and proteins

Step-by-step solution

The cell membrane is mainly composed of lipids and proteins. The major lipids are phospholipids that are arranged in a bílayer. Depending on the ease of extraction, membrane proteins can be classified as integral and peripheral. An improved model of the structure of cell membrane was proposed by Singer and Nicolson (1972) widely accepted as fluid mosaic model.
