Imagine a mugger has approached you in a dark alley. As part of the flight response, your body will release epinephrine (a hormone) to your muscle cells. The release of epinephrine causes the formation of several enzymes that will lead to glucose breakdown to make extra ATP. Extra ATP as chemical energy in your muscle cells will allow you to run from your attacker faster!
Which type of membrane protein will epinephrine bind to in order to elicit this response?
