- The image depicts a fluid mosaic model of the cell membrane.
- Component A represents the phospholipid bilayer, which forms the basic structure of the membrane.
- Component B is a peripheral protein, located on the surface of the membrane.
- Component C is a cholesterol molecule, embedded within the bilayer to modulate fluidity.
- Component D is an integral protein, spanning the entire membrane.
- Component E represents carbohydrate chains attached to proteins (glycoproteins) or lipids (glycolipids), found on the extracellular side.
- Component F indicates the hydrophilic heads of phospholipids facing outward, interacting with aqueous environments.
- Component G shows the hydrophobic tails of phospholipids oriented inward, away from water.
