Question

Your muscles are switched on by releasing calcium ion from the sarcoplasmic reticulum that surrounds your muscle bundles. The Ca2+ binds to a muscle fiber, and that triggers the contraction. To relax the muscle again, Ca2+ must be pumped out, so that the concentration in the muscle returns to 10-6 M, and the concentration in th reticulum is 10-3 M. How much work is required per mole to move calcium ions
up this concentraBon gradient? (Hint: body temp is 37°C)
