WebThere are two other proteins located at the plasma membrane which help to return Ca++ to its basal level inside the cardiac muscle cell. The plasma membrane CaATPase uses ATP to actively pump Ca++ out. The Na+ - Ca++ exchanger transports Na+ into the cell for each Ca++ moved out of the cell (i.e., exchanges Na+ for Ca++). Figure 4. WebMar 26, 2024 · The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment.
