Biochemistry
Every pathway earned, not memorized.
the shape of this subject
Biochem lives at the intersection of memorization and reasoning. Brainback lets memorization be scored on flashcards — and reasoning be trained in Learn mode.
Because biochemistry rewards the students who do the reps — and punishes the ones who outsource them.

Every biochemistry concept Brainback covers.
Add Biochemistry as a Learn subject and every problem in these areas routes to the Socratic tutor — attempt-first, hint-laddered, output-guarded.
What one turn in biochemistry actually looks like.
Attempt → correction → guiding question. No answer. Ever. Verbatim from a beta session.
Michaelis-Menten: at high [S], rate approaches Vmax…
What class of enzyme is this? Which cofactor does it need?

the anti-pattern
What biochemistry looks like when the AI does the thinking.
Answer machines make biochemistry look like a solved problem. It isn't. The exam room reveals whose reasoning was built and whose was rented.
- M1Applying a formula without checking whether the conditions actually hold.
- M2Skipping the sanity check — 'does the sign / magnitude make sense?'
- M3Memorizing steps instead of reasoning about why they're legal.
- M4Reading past the setup and diving straight into computation.
the recall card
What a spaced-repetition card looks like in biochemistry.
Every wrong attempt and low-scored explain-back becomes a card. SM-2 schedules them — the tricky ones come back tomorrow, the solid ones drift out to next week, then next month.
Recall the core concept in your own words. Then apply it to a fresh example under 2 minutes.
