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 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.

The Last Fellow: the doctor who had this service before you was walked out in August, and their coat is still on the office rack. Find their office and their notebook, question the night staff, and make the call on what happened to them, or leave it alone and work your patients.

Studying that doesn't feel like studying. Everything is included: no DLC, no microtransactions.
