Fluid mosaic model

The video explores the cell membrane, highlighting its structure and function. It introduces the fluid mosaic model, explaining how phospholipids, cholesterol, and proteins contribute to membrane fluidity and permeability. Phospholipids form a bilayer with hydrophilic heads and hydrophobic tails, while cholesterol regulates fluidity. Proteins facilitate transport and communication. The balance of fluidity ensures cell stability and controlled substance movement.
