Chapter 18 Lipids

18.8 Cell Membranes

Transport:

diffusion: natural migration from high to low concentration

facilitated transport: utilizes integral proteins (Cl^-,HCO₃^-, and glucose)

active transport:migration from low to high concentration, requires energy to counter concentration gradient (nerve cells:Na⁺, K⁺)
