Integral Proteins:

Proteins that are permanently attached to the cell membrane and typically span across the entire lipid bilayer, playing critical roles in transport and signal transduction.

Cell Membrane:

The semi-permeable membrane surrounding the cytoplasm of a cell, which regulates entry and exit of substances, maintaining the internal environment of the cell
