Mike and Molly just dropped a clear, test-focused breakdown of G protein coupled receptors that covers everything the AAMC expects you to know without the textbook overwhelm.Here's what we walk through:🔬 The full signaling cascade: signal → receptor → transduction → amplification → response → termination🧬 GPCR structure and how G proteins actually get activated (GDP → GTP swap)🚀 Gs pathway: adenylyl cyclase → cAMP → PKA → phosphorylation🛑 Gi pathway: how it inhibits the same cascade🧩 Gq pathway: PLC, calcium signaling, and second messengers📈 Why amplification is the whole point — small signal, massive cellular response⏱️ How your cells know when to shut it all off👁️ Plus a vision callback showing GPCRs in phototransductionWe even hit a classic passage-style example (cholera toxin) to show you how the AAMC actually tests cause-and-effect in these pathways.Next episode: smell & taste and how these senses are built on GPCR signaling 👃Want to learn more?
