Study Notes

Integral proteins are characterized by being embedded in the cell membrane, with their hydrophobic regions interacting with the lipid bilayer.
Peripheral proteins are involved in cell signaling, acting as receptors for external signaling molecules.
One of the primary functions of the cell membrane is to regulate the movement of molecules in and out of the cell.
Integral proteins play a crucial role in facilitating the transport of molecules across the cell membrane.
The integral proteins are responsible for interacting with external signaling molecules, allowing the cell to respond to its environment.
Peripheral proteins are involved in cell signaling and play a role in supporting the cell membrane structure.
A common misconception about peripheral proteins is that they are embedded in the cell membrane, when in fact they are attached to the membrane surface.
Integral proteins contribute to the selective permeability of the cell membrane by forming channels and pores that allow certain molecules to pass through while restricting others.
Peripheral proteins play a supporting role in cell membrane function, helping to regulate the activity of integral proteins and maintain the overall structure of the membrane.
