AC AC Inside C + A Figure 22 A possible scheme for amino acid transport. C is a transport site or carrier; A, an amino acid molecule. C is a more reactive form of the transport site, generated perhaps by the exergonic reaction, x -* y. Reaction of A with C causes not only complexing but also trig- gers a structural change that places the complex CA inside the osmotic barrier (indicated by the shaded band). (Note that A is used here to represent the solute molecule and has nothing to do with the hypothetical A site of the Ehrlich cell.) 61.
