Sodium

Vedclass · Answer

(A) In hormone action,secondary messengers are molecules that relay signals received at receptors on the cell surface to target molecules in the cytosol and/or nucleus.Common secondary messengers include $cAMP$,$cGMP$,$IP_3$ (inositol triphosphate),$DAG$ (diacylglycerol),and $Ca^{2+}$ (calcium ions).Sodium $(Na^+)$ ions do not function as secondary messengers in hormonal signaling pathways; instead,they are primarily involved in maintaining the ionic balance and membrane potential of the cell.Therefore,the correct answer is Sodium.
