Coupling uncoupled systems compared

We can directly compare the dynamic responses of the coupled and uncoupled systems. The fast state X has the respone ... 

This tells us that the reduced magnetic entropy change will be lower in an antiferromagnetic system than in an uncoupled one, as can be seen below, as the spins are not fully saturated below the conditions of lowest temperature and strongest field. The antiferromagnetic coupling in Gd(III)7 is also a hindrance, with behaviour similar to Gd(III)5, when compared to the relevant Brillouin functions. 

Table I shows some data on the lipid-specificity of ATP-synthesis and ATP-hydrolysis. Here we compared proteoliposomes with either soya lecithin (SL), or egg phosphatidyl choline (PC). During ATP-hydrolysis, CCCP was used as an uncoupler it was added at the optimal concentration for both types of proteoliposomes (2 pM). It should be noted that similar results were obtained with other types of uncouplers, e.g. valinomycin plus ammonia [ij. During ATP-hydrolysis, both types of proteoliposomes exhibited comparable activities the coupling ratio (i.e. the ratio of activities with and without uncoupler) was admittedly about 2 times higher in SL-proteoliposomes than in PC-proteoliposomes, but this ratio was in PC-proteoliposomes still higher than in the original system, i.e. chromatophores [6J. However the rate of...
