Ions released from sarcoplasmic reticulum
Webrelease calcium ions and cross-bridge linkages form between actin and myosin, and the cross-bridges pull on actin filaments, shortening the fiber. Finally, the muscle fiber relaxes when myosin heads release from actin, breaking the cross-bridges (ATP is needed, but is not broken down) and when calcium ions are actively transported (requiring ATP … WebThis book was released on 2012-12-06 with total page 576 pages.
