You will LOSE points (from the total correct) for incorrect answers. This is to discourage guessing. the positive ion promotes exocytosis the positive ion promotes v-SNARE and t-SNARES to produce neurotransmitters the positive ion promotes muscle contraction the positive ion helps repolarize the membrane the positive ion binds calmodulin the positive ion binds to synaptotagmin

Explanation / Answer

Calcium ions plays an important role in extracellular signalling, this is done by their entry in the cell cytosol wherein they exert allosteric regulatory effects on various proteins etc. They also can lead to activation of various ion channels signalling pathways etc. The various physiological role played by calcium ions are muscle contraction and binding to calmodulin(regulatory protein).
