A)The sarcomeres of muscles are known to release Ca2+ from inside the cell to outside during the process of muscle contraction. Mammalian sarcomeres maintain a membrane potential of 70 mV (negative intracellular potential), an intracellular concentration of Ca2+ of 40 mM, and an extracellular concentration of 1.2 mM at 37ºC. Calculate the DG associated with the movement of calcium from inside the sarcomere to outside. Is this process spontaneous given these conditions?
