WebbActive transport requires energy, while passive transport does not. Active transport is mainly used for the movement of molecules and/or solutes from outside the cell into the cell, while passive transport is primarily used for the movement of molecules outside of the cell.

WebbIs water passive or active transport? 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. WebbActive transport uses energy to move molecules against a concentration gradient.
