What moves the calcium back into the sarcoplasmic reticulum? Relaxation. The calcium pump allows muscles to relax after this frenzied wave of calcium-induced contraction. … Powered by ATP, it pumps calcium ions back into the sarcoplasmic reticulum, reducing the calcium level around the actin and myosin filaments and allowing the muscle to relax.
What pumps calcium back into the sarcoplasmic reticulum after muscle contraction? Ca2+-ATPase specifically maintains the low cytoplasmic calcium concentration of resting muscle by pumping calcium into the sarcoplasmic reticulum; subsequent release is used to initiate contraction.
What membrane transport mechanism is used to return calcium to the sarcoplasmic reticulum? Most of this calcium moves back and forth across the sarcoplasmic-reticulum membrane in cycles of contraction and relaxation. The channel responsible for release from the sarcoplasmic reticulum is the ryanodine receptor, whereas Ca2+-ATPase effects reuptake in an ATP-dependent manner.
Which helps bind Ca2+ in the sarcoplasmic reticulum? Calsequestrin is a calcium-binding protein that acts as a calcium buffer within the sarcoplasmic reticulum. The protein helps hold calcium in the cisterna of the sarcoplasmic reticulum after a muscle contraction, even though the concentration of calcium in the sarcoplasmic reticulum is much higher than in the cytosol.
