Give the biochemical composition of plasma membrane. How are liPid molecules arranged in the membrane?

Explanation

### Step-by-Step Text Solution:

1. **Biochemical Composition of Plasma Membrane**:
The plasma membrane is primarily composed of lipids and proteins. The major lipid component is phospholipids, which form a bilayer. Other lipids present include glycolipids and steroids. Proteins are embedded within this lipid bilayer, contributing to the membrane's functionality.

2. **Fluid Mosaic Model**:
The structure of the plasma membrane is explained by the fluid mosaic model. This model describes the membrane as a sandwich-like structure where the lipid bilayer acts as the bread, and the proteins are the various toppings that are embedded within or attached to the lipid bilayer.
