Biological membrane models

Biological membrane models describe how cell membranes are organized and function. The most common model is the fluid mosaic model, which envisions the membrane as a flexible layer of phospholipids with embedded proteins. Phospholipids form a bilayer, acting like a flexible wall that separates the cell from its environment. Proteins embedded in this bilayer serve various roles, such as transport, communication, and structural support. This model emphasizes that the membrane is dynamic, allowing components to move laterally, facilitating essential processes like nutrient intake and waste removal, and maintaining cell integrity.
