clearer thanks to work from Ebashi and Lipmann. (Burgoyne and Petersen‚ 1997). Calcium signalling determines whether or not a cell is activated. It is determined by calcium-ON and calcium-OFF mechanisms. Calcium-ON is responsible for pouring Ca2+ into the cytoplasm‚ from both internal and external sources. The calcium-OFF mechanism however removes cytoplasmic Ca2+ by pumping it out of the cell‚ or back into the internal stores (Heldin and Purton‚ 1996).
