Figure 9. Cross-bridge distribution.

Calculated cross-bridge distribution in muscle actin reconstituted myocardium (open bars), 2Ac reconstituted myocardium (filled bars) and 4Ac reconstituted myocardium (hatched bars). The bars labelled Det are the sum of all detached states (MS, MDP) and weakly attached states (AMS, AMDP) and the same as X₃₄ in scheme 1. The bars labelled Att are the sum of all strongly attached states (AM, AM*S, AM*DP, AM*D, and AMD). The estimate of the error for this plot is about 20% of the value.
