Total Biochem

Study — everything before the exam (and after) - 3,300+ Practice Items: 37 drill topics from amino acids to metabolic integration — enzyme kinetics, the pathways, inborn errors, lab methods, the central dogma, and more. Built for course exams, MCAT review, and anyone coming back to biochemistry. - A Lesson for Every Topic: the rules, the traps, and figures drawn the way the exam draws them — kinetics plots and pathway boards you can actually read. - Flashcards & Cheat Sheets: 31 decks and 550+ cards with spaced review, plus pinned reference sheets — the pKa ladder, the control points, the compartments, the quick reference. - Mock Exams & the Course Map: build a practice test with pace presets and exam-style deferred feedback, fix what you missed, and clear units on the Course Map. - Mechanisms, Arrow by Arrow: 15 step-by-step walkthroughs — serine proteases, PLP, TPP, kinases, aldolases — one electron push at a time. Play — the bonus: a clinical mystery - Work the Night Service: seven floors of a hospital, from the nursery to the exercise lab. Patients arrive with a story — an infant who vomits after fruit juice, a runner with cola-colored urine — and your job is to find the enzyme that failed. - Read the Labs Yourself: order tests against a clock, a reagent budget, and one tube of blood that never refills. The instrument shows you the trace; it never tells you what it means. Misread it, and the wrong number goes in the file. - Place the Block: pin a block on one step of the pathway board and see what the body would do — what piles up, what runs out. When it matches the labs, you call the attending. Three answers, one phone call, no partial credit. - A Hospital with Secrets: every floor has its own story — a swapped formula lot, a visitor after hours, a signature from a clinic that closed last year. Look around, ask the right person, and find out. Studying that doesn't feel like studying. Everything is included: no DLC, no microtransactions.
