The Major Functions of the Cytoplasmic Membrane (Over View)

Figure 4.9

2.Improved transport of molecules into the cell via “membrane-spanning transporters” – requires use of energy

1.Transport (permeabiliy) of different molecules into the cell via the membrane is poor (next table)

3.Protons(H+) are separated from hydroxyl ions (OH-) --> responsible for Proton Motive Force (PMF) or energy generation
