The non polar portion of the plasma membrane are composed of:     phosphate headgroups     phosphate tails     fatty acid headgroups     fatty acid tails
Identify how each of the following would pass through the plasma membrane: gases, large polar molecules, charged molecules (like ions), hydrophobic molecules, and small polar molecules. Be specific.
"Tight junctions perform two distinct functions: they seal the space between cells to restrict paracellular flow and they fence off plasma membrane domains to prevent the mixing of apical and basolateral membrane proteins" is true or false.
