Study Notes
The Cytoplasmic Membrane
- The cytoplasmic membrane is 7 nm thick and composed of phospholipid and protein molecules.
- It has a distinctive structure with 2 dark bands separated by a light band.
- Prokaryotic membranes, excluding mycoplasmas, lack sterols.
Functions of the Cytoplasmic Membrane
- Acts as an osmotic or permeability barrier, allowing for passive and facilitated diffusion.
- Performs other functions, but these are not specified.
