WebThere the calcium ions interact with the neurotransmitter containing vesicles (membrane-bound containers) causing them to fuse with the cell membrane, and release the neurotransmitters into the synaptic cleft. Other ions like sodium or potassium do not interact with the vesicles, which is why the voltage-gated calcium ion channels are necessary. WebThe sarcoplasmic reticulum ( SR) is a membrane -bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca 2+ …
