How do the following molecules get through the
cell membrane (simple diffusion, facilitated diffusion, active transport,
or two of these mechanisms): water, glycerol, O2, CO2,
glucose, amino acids, ions, oils, ethanol, steroids?
- simple diffusion- H2O, glycerol, small nonpolar (O2, and CO2), large nonpolar (oils, steroids)
- facilitated diffusion- glucose, water, ions,glycerol, animo acids
- active transport- glucose, ions
