Hi guys, got something that's puzzling me a little. This is from my SMP, so it's not exactly an MCAT question but I remember something similar asked by AMCAS anyway
I understand that insulin stimulates glycogen formation/ glycolysis, and glucagon stimulates gluconeogenesis and glycogenolysis.
What confuses me is HOW cahill/cori cycles work
Let's theoretically say that someone is starving and glucagon is released, and there is a very low insulin level. That person should start producing free glucose in the liver, just as the diagram shows. Why however, does the muscle/brain/whatever cell undergo glycolysis. I understand that it NEEDS to, but I don't understand the contradictory regulation of this
Thanks!
