Isometric force responses following flash photolysis of caged-ATP were measured from skinned preparations of the catch muscle anterior byssus retractor of Mytilus (ABRM). When fibres were transferred from Ca2+-free to Ca2+-containing rigor solution (pCa<4) the force remained low, but flash photolysis produced an extended force increase (half-time, 0.30±0.07 s, n=6). When Ca2+-activated fibres were transferred to a Ca2+-free rigor solution, their force remained at a high level. Flash photolysis… CONTINUE READING
