Simple diffusion is a process where a substance passes through a membrane without the help of an integral membrane protein.

The force which drives the substance from one side to the other side of the membrane is called as the force of diffusion. And while passing through it, it penetrates into the hydrophobic core of the phospholipid bilayer.

The types of molecules that can do this are:
  • Ethanol
  • Carbon dioxide
  • Oxygen
