Experimental investigation of the bound dissipation function: change of the psi u-function during the growth of yeast.
By means of a microcalorimeter (direct calorimetry) and a Warburg-apparatus (indirect calorimetry) that part of the dissipation of a growing culture of yeast cells which remains irreversible in the cells is determined (psi u). The course of the psi u-function with time correlates with the increase of the specific cell concentration being conditioned by the growth phase of the culture but similar for fermentative and respirative metabolism.
