Analyze what is meant by \"the transport of an ion across amembrane is determined by its electrochemical potential.\" In doingthis, describe the factors that must be taken into account whenconsidering whether the transport of a charged solute across amembrane is endergonic or exergonic. Consider how this compares touncharged solutes.Compare simple diffusion and osmosisGiven that most cells are hypertonic relative to theirenvironment, describe how this in turn affects the movement ofwater into cells and the adaptations of animal and plantcells.Discuss the reasons for the differences in transport rateobserved for facilitated carriers compared to channels. Considerhow the mechanism via which these proteins allow the movement ofsolutes will in turn affect the rate at which the solutes aretransported.

Compare simple diffusion and osmosis
Given that most cells are hypertonic relative to theirenvironment, describe how this in turn affects the movement ofwater into cells and the adaptations of animal and plantcells.
Discuss the reasons for the differences in transport rateobserved for facilitated carriers compared to channels. Considerhow the mechanism via which these proteins allow the movement ofsolutes will in turn affect the rate at which the solutes aretransported.

Such transport is governed by delta G or change in Gibbs free energy if that is negative the transport is favorable Now the formula for delta G for charged and uncharged solutes are Charged Delta G inward RT ln SINSIDE SOUTSIDE zFV where R is gas constant T
