2. The Cell Membrane vs. The Stadium Exterior
2.1 Cell Membrane: The Protective Barrier
The cell membrane, also known as the plasma membrane, is the outermost layer of a cell, separating the cell’s interior from its external environment. Its primary function is to protect the cell and regulate the movement of substances in and out. The cell membrane is composed of a lipid bilayer, made up of phospholipids, cholesterol, and proteins.
The phospholipid bilayer consists of two layers of phospholipid molecules, with the hydrophilic (water-attracting) heads facing outward and the hydrophobic (water-repelling) tails facing inward. This arrangement creates a barrier that prevents the free passage of water-soluble substances, ensuring that only specific molecules can enter or exit the cell.
Proteins embedded within the lipid bilayer perform various functions, including transporting molecules across the membrane, acting as receptors for signaling molecules, and facilitating cell-to-cell communication. Cholesterol molecules are interspersed among the phospholipids, helping to maintain the membrane’s fluidity and stability.
