WebThe plasma membrane occupies a pivotal position between these two compartments, where selective channels regulate influx of Ca(2+), and specific carriers pump the ion back into the wall. In addition we draw attention to different factors, which either respond to the wall or are present in the wall, and usually generate elevated [Ca(2+)] in the cytoplasm. WebThe flow of ions through membrane channels is dependent on the establishment of ion gradients across the plasma membrane. All cells, including nerve and muscle, contain ion pumps (discussed in the next …
