Explain the difference between ion channels and G proteins as they relate to signal transduction and targets of medications.

ION CHANNELS AND G PROTEINS

This Discussion will allow you the opportunity to engage with your peers to explore the difference between ion channels and G proteins. You will be able to apply this understanding to a specific patient question. Additionally, please reply to your peers with additional information and sources to either support or challenge responses.
