Membrane lipids can move laterally with relative ease, but flip-flopping between layers takes much longer. True or False? The potassium channel is specific for potassium and not sodium because the pore in the channel is not large enough to fit sodium. True or False? The direction of spontaneous calcium transport depends only on its concentration on both sides of the membrane. True or False?
