Ca2+: micromolar inside. Thousand-fold greater outside.
Organic anions: 15:1 inside
channels vs transporters - ANSWER-channels move water or ions and electrode transporters are solute carriers or pumps
Permeability for passive diffusion - ANSWER--Ions (K+, Na+, HCO-, Ca2+, Cl-) do not cross the membrane
-hydrophobic molecules (O2, N2, CO2) pass freely
-small, uncharged, polar molecules like glycerol can move to a small extent
-large, uncharged, polar molecules like glucose and sucrose do not cross by passive diffusion
True or false: Channels only move things passively - ANSWER-True
