In this Jack Westin MCAT Podcast episode, Mike and Molly break down MCAT signaling cascades with a clear, test-focused walkthrough of G protein–coupled receptors (GPCRs). You’ll learn the core GPCR structure, how GDP → GTP activation works , why signaling pathways create amplification, and how cells shut signals off with built-in termination steps.

We cover the high-yield cAMP pathway in detail, including Gs vs Gi, adenylyl cyclase → cAMP → protein kinase A (PKA), plus the key ideas behind the Gq pathway (PLC and calcium signaling). We also connect GPCR signaling to common MCAT contexts like hormones, fast cellular responses, and a classic passage-style example (cholera toxin) to show how the AAMC tests cause-and-effect in pathways.

In this episode, you’ll learn:

🌊 What a signaling cascade is: signal → receptor → transduction → amplification → response → termination

🧬 GPCR basics (membrane receptor + G protein alpha/beta/gamma)

🔄 How GPCRs activate G proteins (GDP swapped for GTP, then subunits dissociate)

🚀 The Gs pathway: adenylyl cyclase → cAMP → PKA → phosphorylation

🛑 The Gi pathway: inhibiting adenylyl cyclase and lowering cAMP

🧩 The Gq pathway: PLC, second messengers, and calcium

📈 Why amplification matters (small signal, big cellular response)

⏱️ How signaling is shut off (GTP hydrolysis + cleanup of second messengers)

👁️ Vision callback: how GPCR-style signaling shows up in phototransduction

Next up: Smell & taste and how these senses rely heavily on GPCR signaling

In this Jack Westin MCAT Podcast episode, Mike and Molly break down how vision works from start to finish, tying together physics (optics) and biology (retina + neural pathway) in the exact way the MCAT can test it across Chem/Phys, Bio/Biochem, and Psych/Soc.

You’ll learn how light refracts through the cornea and lens, why the cornea does most of the refraction, and how the eye focuses images onto the retina. Then we walk through transduction in the retina (rods and cones → bipolar cells → ganglion cells), how signals travel through the optic nerve, cross at the optic chiasm (by visual field, not by eye), relay through the lateral geniculate nucleus (LGN), and arrive at the primary visual cortex in the occipital lobe for perception.

We also cover high-yield MCAT optics and vision topics, including:

Cornea vs lens refraction and why LASIK reshapes the cornea

Fovea and why cones drive high-acuity color vision

Rods vs cones (low light vs color/detail)

Myopia vs hyperopia and which lenses correct each (diverging vs converging)

The blind spot and why it exists

Why real images are inverted on the retina and how the brain interprets vision

🎧 Listen, take notes, and use this as a clear, connected review for any MCAT passage that mixes optics + anatomy + perception.

In this episode, we break down the Jack Westin daily CARS passage “Sibling Relationships” (Feb 11) sentence-by-sentence to train you how to:

Identify key ideas in each sentence and paragraph

Track repeating themes across short paragraphs

Lock in the main idea (without bringing in your own opinions)

Build a clean passage map you can use on test day

Avoid the #1 trap: letting your personal experience change your answers

We also unpack the passage’s biggest throughline: how sibling competition, family roles, and birth order connect to personality traits (first-born vs last-born vs middle child), plus terms like de-identification and finding a “niche” in the family environment.

✅ Try the passage before you listen (recommended): pause here, attempt it, then come back and follow along with the walkthrough.
