Contour plots of the goodness of fit parameter R2 (= 0.96) for water transport response in X. helleri sperm cells in three different media: HBSS with no CPAs (A), HBSS with 14% glycerol (B), and HBSS with 10% DMSO (C). 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.
