Figure 6. The effects of phosphate on the sum (A) and the product (B) of 2πb and 2πc.

The data were obtained from the same experiments shown in Fig. 2. ▵, 2Ac reconstituted myocardium (n= 13–15); ○, 4Ac reconstituted myocardium (n= 9); ♦, muscle actin (MAc) reconstituted myocardium (n= 13–14). Continuous curves are based on eqns (2) and (3) with best fit parameters. Units of the ordinates are s⁻¹ (A) and s⁻² (B).
