WebThe cross bridge cycle ends when Ca2+ are actively transported back into the sarcoplasmic reticulum. The cycle repeats as long as the binding sites on actin remain exposed, and both Ca2+ and ATP are available. A person dies, and within hours, the skeletal muscles develop a locked contraction known as rigor mortis.
