Problem: Write a response "Thank you for your brief and clear explanation of the differences between ion channels and g proteins. Although both iron channels and g proteins play an essential role in signal transduction, they however, operate differently. Iron channels allow direct ion transportation across the plasma membrane to facilitate cell membrane potential regulation, contraction of the muscles, nerve conduction, and neural communication (Alexander et al., 2021). On the hand however, G proteins work though a more complex mechanism involving GPCR activation, and act as intermediaries, triggering downstream responses (Inanobe & Kurachi, 2014).
