Integral proteins are a type of membrane protein that are permanently attached to the cell membrane.
These proteins span across the lipid bilayer, meaning they extend from one side of the membrane to the other.
Integral proteins play crucial roles in various cellular processes, including acting as channels or transporters for molecules to pass through the membrane.
They differ from peripheral proteins, which are temporarily associated with the lipid bilayer and can be easily removed.
Understanding the structure and function of integral proteins is essential for comprehending how substances move in and out of cells and how cells communicate with their environment.
