The plasma membrane of muscle cells help maintain a concentration gradient of calcium ions Ca2 between muscle cell s cytoplasm and extracellular fluid When a muscle cell receives a signal to contract Ca2 moves down this concentration gradient passing from the extracellular space into the cytoplasm of the cell Which of the following is the most likely mechanism by which Ca2 move across the plasma membrane during muscle cell contraction
