Data from intact and skinned muscle fibers support the hypothesis that cross-bridge interaction modifies TnC structure and calcium activation. Barnacle single muscle fibers microinjected with the calcium bioluminescent photoprotein, aequorin, show extra light (calcium) when shortened during the declining phase of the calcium transient. The extra calcium is increased by increases in muscle force, and its decline is delayed at higher forces. This extra calcium occurs probably because calcium… CONTINUE READING
