Understanding the Figure
The accompanying figure depicts a simplified representation of a cell membrane, illustrating the arrangement and interactions of various components within it.
The membrane is composed of a phospholipid bilayer, with hydrophilic heads facing outwards and hydrophobic tails facing inwards. Embedded within this bilayer are various proteins, including cholesterol molecules.
Components and Locations
- Phospholipids:Form the bulk of the cell membrane, creating a fluid and flexible barrier.
- Cholesterol:Embedded within the phospholipid bilayer, it helps maintain membrane fluidity and rigidity.
- Integral proteins:Span the entire membrane, facilitating the transport of molecules across the membrane.
- Peripheral proteins:Attached to the surface of the membrane, they perform various cellular functions.
