  • Our body have muscles these muscles are made up of muscle cell called myofibril , these myofibril contain storehouse of Ca²+ in the sarcoplasmic reticulum during contraction off muscle the calcium ions are required . These calcium ion help in removing troponin C so that myosin head can bind to it . Therefore the answer for this question becomes
