Abstract
Electrokinetic studies of aqueous solutions of urea, glucose, urea-glucose mixture (urea concentration increasing and glucose fixed) and glucose-urea mixture (glucose concentration increasing and urea concentration fixed) have been carried out across urinary bladder membranes of goat. Results have been analysed using methodology of non-equilibrium thermodynamics. It has been found that energy conversion maxima and degree of coupling for mixtures is higher than urea and glucose solutions. It has also been found that in the case of urea-glucose mixtures, the value of maxima and degree of coupling first decreases and then increases with increase in concentration while in the case of glucose-urea mixture, the trend is not definite. With urea solutions only, both these values increase with increase in concentration. It has been observed that energy conversion maxima and degree of coupling for urine is much higher as compared to other permeants. It appears that second order phenomenological coefficient L112 is related with degree of coupling (qe) as the trend of two is quite similar.
