Crossing a phospholipid bilayerdepends on the ­size
solubility
polarity(nonpolar/polar)
Nonpolar, even distribution
Polar, uneven distrubution

If it is to big or insoluble it will go through either channel protein e.g. (calcium) water soluble
a passive process
Or a carrier protein (glucose) (carrier…
