Comparison of the effect of Neb versus the effect of Tpm (in the presence of the troponin complex and Ca2+) on active tension and the kinetic constants. The ratio (after:before Neb or Tpm addition) of the parameters indicated are plotted (left ordinate). The right ordinate is log10 of the ratio. Active tension for Neb fibers was corrected for the thin-filament length difference before the ratio was taken. Errors are propagated. K5 is the Pi association constant, hence 1/K5 is used to describe the Pi dissociation step 5. The data on Tpm were taken from Fujita et al. (2002).
