Question

Explain how ca2+ helps in being mediators of harmons

Answer 1

Calcium (Ca2+) ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transductionresulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors
