The cell membrane is a selectively permeable barrier that surrounds the cell, maintaining homeostasis by controlling the movement of substances in and out of the cell. It is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates that facilitate communication and transport functions.

Homeostasis is the physiological process by which biological systems maintain stability and equilibrium in response to changing external conditions. It is essential for the survival of organisms, enabling them to regulate internal environments such as temperature, pH, and ion concentrations to ensure optimal functioning.

The phospholipid bilayer is a fundamental component of cell membranes, consisting of two layers of phospholipids with hydrophilic heads facing outward and hydrophobic tails facing inward, creating a semi-permeable barrier. This structure is crucial for maintaining cell integrity and facilitating the selective transport of substances in and out of cells.

Cholesterol is a waxy, fat-like substance found in all cells of the body, essential for the production of hormones, vitamin D, and substances that help digest foods. While necessary for health, high levels of cholesterol in the blood can increase the risk of heart disease and stroke due to the buildup of plaques in arteries.

Carbohydrates are organic compounds found in foods and living tissues, primarily serving as a major energy source for the body. They are classified into simple and complex forms, with their digestion and metabolism playing a crucial role in maintaining blood glucose levels and overall health.
