Turn your own material into USMLE Step 1 biochemistry flashcards

Ready-made decks rarely match the lectures and review book you actually use. Upload your PDFs, slides, notes, or photos of pages and get flashcards for the exact pathways you need to know.

Why custom decks beat generic ones for Step 1

Biochemistry on Step 1 rewards precise recall of pathways, enzymes, cofactors, and inherited disorders, so USMLE Step 1 biochemistry flashcards work best when they follow the material you are studying. DeckOwl builds cards from your own files, so each pathway card matches the lecture or chapter that covered it.

Pathway cards with the enzyme, its regulation, and the clinical correlate on the back
Cards generated from PDFs, slides, typed notes, or photos of pages
Spaced repetition schedules reviews so weak cards come back sooner
Free plan includes 3 generations per month; Plus adds unlimited generations and Anki export

Example USMLE Step 1 biochemistry flashcards

What is the rate-limiting enzyme of glycolysis?Phosphofructokinase-1 (PFK-1), which is inhibited by ATP and citrate and activated by AMP and fructose-2,6-bisphosphate.

Which vitamin is the cofactor for transketolase, and which lab test reflects its status?Thiamine (B1), as thiamine pyrophosphate; erythrocyte transketolase activity is the assay that reflects its status.

Which enzyme is deficient in classic galactosemia?Galactose-1-phosphate uridylyltransferase (GALT), which leads to accumulation of galactose-1-phosphate.

What is the rate-limiting enzyme of cholesterol synthesis?HMG-CoA reductase, which is the target of statin drugs.

Which enzyme is deficient in Lesch-Nyhan syndrome, and which pathway does it affect?HGPRT (hypoxanthine-guanine phosphoribosyltransferase) in purine salvage, which leads to overproduction of uric acid.

Generate the full set

Built from your material

Upload PDFs, DOCX or PPTX files, typed notes, or photos of pages. Text recognition reads scanned pages too.

Spaced repetition

Cards return on a schedule so enzymes, regulators, and deficiency states stick well before test day.

Export to Anki

Plus users can export to Anki or CSV, so biochemistry cards sync into the deck you already study from.

How it works

Upload your notes

Add the lecture slides, PDF chapters, or photos of your review pages for biochemistry.

Review the cards

Check the generated flashcards, remove vague ones, and keep the pathway cards that matter for Step 1.

Study on a schedule

Spaced repetition brings back the cards you miss so pathways stay fresh across weeks of review.

Start with the topics where you lose points, such as glycolysis regulation, vitamin cofactors, and purine metabolism. Review the generated cards, cut any that are too broad, and let spaced repetition bring back the ones you keep missing.

Frequently asked questions

How many flashcards should I make for USMLE Step 1 biochemistry?

Aim for one card per distinct fact, such as a single enzyme, cofactor, or regulator, rather than cards filled with whole paragraphs. A focused set covering the core pathways is more useful than a huge deck you never review.

Which biochemistry topics should I prioritize for Step 1?

Start with metabolic pathways and their regulation, vitamins and cofactors, enzyme kinetics, and inherited metabolic disorders. Then check your practice question results to find the areas where you miss the most.

Can I export my flashcards to Anki?

Yes, export to Anki and CSV is included in the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study in the browser but does not include exports.

Is there a free plan to try it first?

Yes, the free plan includes 3 generations per month and browser study, and no credit card is needed to start. Students can get 40% off with a school email.
