Contour plots of the goodness of fit parameter R2 (=0.98) for water transport response in X. maculatus sperm cells in three different media: HBSS with no CPAs, HBSS with 14% glycerol and HBSS with 10% DMSO. Note that the best fit parameters (Table 2) are represented within the contours by a “*” (absence of CPAs), “#” (with 14% glycerol) and “ &” (with 10% DMSO). The membrane permeability at 0 °C, Lpg (or Lpg [cpa]) (m3/Ns) is plotted on the y-axis while the apparent activation energy of the membrane, ELp (or ELp [cpa]) (kJ/mol) is plotted on the x-axis.
