Figure S10.

Changes in twitch tension from Fig. 5 B (black line) by ±20% variation in ADP release rate, ${\mathit{k}}_{\mathbf{+}\mathbf{D}}^{\mathbf{o}}\mathbf{.}$ Increase in $k_{+D}^o$ only slightly increases the peak of the twitch tension and the relaxation starts at earlier times. The superscript o is omitted from the figure display for clarity.
