However, a warning: Do not buy Sketchy Biochem alone. The interface is designed for the entire suite. If you buy the "Biochemistry ONLY" add-on, you lose the cross-integration with Pharmacology (e.g., how Statins inhibit HMG-CoA reductase, which is drawn in the Cholesterol sketch). The magic happens when you realize the "Gym" from glycolysis sits right next to the "Gluconeogenesis Restaurant" (the liver) in the metabolic map. Yes, for the visual learner. If you have ever looked at a metabolic map and felt a sense of dread, you need Sketchy.
Disclaimer: Always cross-reference visual mnemonics with a primary source like First Aid for the USMLE. Sketchy is a supplement, not a syllabus. sketchy medical biochemistry
And that is why you pass the boards.
If you prefer understanding the chemistry of why a reaction happens (electronegativity, resonance stabilization), stick to BnB (Boards and Beyond) or Kaplan. However, a warning: Do not buy Sketchy Biochem alone
Use Boards and Beyond (or Ninja Nerd) to conceptually learn the pathway. Then, 48 hours later, watch the Sketchy video to lock the enzymes into your long-term memory. Conclusion The Krebs cycle is not a circle; it is a car wash. Glycolysis is not a list of 10 steps; it is a gym with a persistent thief. The Electron Transport Chain is not a series of complexes; it is a hydroelectric dam where Complex IV is a hungry shark waiting for oxygen. The magic happens when you realize the "Gym"
