In Episode 27, we wrap up our Metabolism series by diving into one of the most testable—and often misunderstood—topics on the MCAT: The Electron Transport Chain (ETC) and Oxidative Phosphorylation.
We cover everything you need to know for MCAT success:
🔬 What You’ll Learn:
Where ETC happens: The inner mitochondrial membrane
Complex I vs. Complex II: NADH vs. FADH₂
The secret identity of SDH (succinate dehydrogenase)
How proton gradients drive ATP production
Why uncouplers like 2,4-DNP are dangerous
Why cyanide is lethal (hint: Complex IV)
Final ATP yields from NADH and FADH₂ (30–36 total!)
📚 Pro Tip: Make sure to review Redox and Thermodynamics before watching this episode.
Next up: We'll break down alternative fuel sources—like proteins, fats, and ketones—in our upcoming non-glucose metabolism episode!
