Role of Ca+ (calcium ions) and ATP (adenosine triphosphate) in muscle contraction and relaxation. Introduction: Muscle contraction and relaxation is regulated by the actin-myosin cross-bridge formation. The actin proteins are present in the light filaments and myosin protein, in dark filaments. The light bands overlap the dark bands and result in the contraction of muscle.
