Ah, I wish I could give you a proper step-by-step, but truthfully, my own biology notes from school are mostly decorated with worried doodles about the PSC! As I recall, carbs start in the mouth with something called amylase, proteins get tackled in the stomach, and fats—well, they mainly get broken down in the small intestine with bile and enzymes. My specific regret is that I only ever truly digested this while trying to tutor my neighbour's son last week, frantically re-learning from his textbook in the quiet of the 6 AM library, with my flask of black tea as witness.
