Study Notes

Cell Surface Membrane

Cell membrane is the term used to describe the barrier around the edge of a cell.
The cell surface membrane controls the movement of substances into and out of the cell.
It is a selectively permeable barrier, meaning it allows some substances to pass through while blocking others.
This membrane is composed of a phospholipid bilayer with embedded proteins.
Phospholipids form a double layer with their hydrophilic heads facing outwards and hydrophobic tails facing inwards.
Proteins within the membrane serve various functions, including transport, recognition, and communication.
The cell surface membrane helps maintain a stable internal environment within the cell.
The unique arrangement of proteins on the cell surface membrane acts as a recognition site for other cells and molecules.
Cells are 3-dimensional structures and understanding their spatial arrangement is essential for comprehending their function.
If the cell surface membrane was absent, the cell would lose its structural integrity, be unable to regulate its internal environment, and ultimately die.
