Integral proteins span the entire thickness of the membrane, creating channels or pores that allow specific ions and molecules to pass through. This selective permeability is crucial for maintaining homeostasis.
How Integral Proteins Enable Selective Transport and Maintain Homeostasis
The structure of a cell membrane is a fundamental concept in biology, defining the physical boundary that separates the internal components of a cell from its external environment. This model describes the membrane as a fluid combination of various components, including phospholipids, cholesterol, and proteins.
Each phospholipid molecule possesses a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails. Cholesterol and Carbohydrates Cholesterol molecules are interspersed among the phospholipids in the membrane, playing a critical role in modulating its fluidity.

Nicolson in 1972, remains the most widely accepted explanation of the cell membrane's structure. Furthermore, the presence of specific receptor proteins allows the cell to detect and respond to hormones, neurotransmitters, and other signaling molecules, enabling complex physiological processes.
