Biochemistry my friend It's time to study you again Mechanisms that I need to know Are the things that really stress me so "Get these pathways planted firmly in your head," Ahern said Let's start with ep-inephrine
Membrane proteins are well known Changed on binding this hormone Rearranging selves without protest Stimulating a G alpha S To go open up and displace its GDP With GTP Because of ep-inephrine
Active G then moves a ways Stimulating ad cyclase So a bunch of cyclic AMP Binds to kinase and then sets it free All the active sites of the kinases await Triphosphate Because of ep-inephrine
Muscles are affected then Breaking down their glycogen So they get a wad of energy In the form of lots of G-1-P And the synthases that could make a glucose chain All refrain Because of ep-inephrine
Now I've reached the pathway end Going from adrenalin Here's a trick I learned to get it right Linking memory to flight or fright So the mechanism that's the source of anxious fears Reappears When I make ep-inephrine
