In cells, it is common for solutes to be maintained at different concentrations on opposite sides of a membrane, including the plasma membrane or an Diffusion across a biological membrane is called passive transport. The target molecule binds to the gated carrier protein and, in response, the carrier protein opens up - this allows the target molecule to enter. However, because they are charged or polar, they can't cross the phospholipid part of the membrane without help. - The energy of activation must be overcome in order for a reaction to proceed.
