It is utilised by molecules that are unable to freely cross the phospholipid bilayer (e.g. large, polar molecules and ions) This process is mediated by two distinct types of transport proteins – channel proteins and carrier ... WebbHowever, active transport requires energy as the substances involved move against the concentration gradient, from low to high concentration. This energy is derived from ATP (adenosine triphosphate), energy-rich molecules in living cells.

Water crosses cell membranes by passive transport and by secondary active cotransport along with ions. While the first concept is well established, the second is new. The two modes of transport allow cellular H2O homeostasis to be viewed as a balance between H2O leaks and H2O pumps.
