Ever wonder how your body kicks into high gear when you’re in danger? In this video, we dive deep into the world of cell communication. We’re focusing on how the hormone epinephrine (AKA adrenaline) signals your liver cells to release energy in those intense “fight-or-flight” moments. This will let us explore G-protein coupled receptor systems, which are important for understanding life, and for crushing it in AP Bio.
