WebThere are two phases of the insulin secretion, the first phase involves the L-type Ca+2 channels and the second phase involves the R-type Ca+2 channels. The Ca+2 influx generated by R-type Ca+2 channels is not enough to cause insulin exocytosis, however, it increases the mobilization of the vesicles towards the cell membrane.
