Why build your own biology unit 3 and 4 deck

Ready-made decks rarely match the syllabus your instructor used, and unit numbering changes between courses. A Quizlet-style biology unit 3 and 4 flashcard set made from your own slides and notes covers the exact terms and diagrams your test will ask about.

Works with PDF, DOCX, PPTX, plain text and photos of pages
Spaced repetition schedules reviews around what you forget
Free plan includes 3 generations per month, studied in the browser
Plus adds unlimited generations and exports to Anki and CSV

Example flashcards for cellular energy and the cell cycle

What is the net ATP yield of glycolysis per glucose molecule?2 ATP, since 4 are produced and 2 are used in the investment phase. It also yields 2 NADH.

Where do the light-dependent reactions of photosynthesis occur?In the thylakoid membranes of the chloroplast, where they produce ATP, NADPH and oxygen.

What are the three phases of interphase in the cell cycle?G1, S and G2. DNA is replicated during the S phase.

What does one turn of the Krebs cycle produce per acetyl-CoA?3 NADH, 1 FADH2, 1 ATP (or GTP) and 2 CO2, because the cycle runs once for each acetyl-CoA.

What is a cell cycle checkpoint?A control point that checks for DNA damage and proper chromosome attachment before the cell continues dividing.

Generate the full set

Built from your material

Upload PDFs, DOCX, PPTX, plain notes or photos of pages, and the flashcards come from what your instructor actually covered.

Spaced repetition

Cards you miss come back sooner, and cards you know fade into longer gaps, so review time goes where it is needed.

Export when you need it

Plus users can export to PDF, DOCX, Anki or CSV, so the same deck works for printing or another study app.

How it works

Upload your unit materials

Add the slides, readings or notes for biology units 3 and 4, or snap clear photos of printed pages.

Generate flashcards

DeckOwl reads the text and creates question and answer cards covering the key terms and processes.

Study and review

Work through the deck in your browser and let spaced repetition schedule what you see next.

Start with the material you already have. Cards built from lecture slides or your own summaries tend to be more specific than generic sets, so you can spot gaps quickly and add missing topics by uploading another file.

Frequently asked questions

What topics are usually in biology units 3 and 4?

It depends on your course, but many introductory and AP-style biology sequences cover cellular energy such as photosynthesis and cellular respiration, and cell communication or the cell cycle. Check your syllabus, then upload those lecture slides so the flashcards match your exam.

How many flashcards should I make for one biology unit?

Aim for one card per key term, process step or diagram label, which often means 40 to 100 cards for a unit. Review a small batch daily instead of trying to memorize the whole set the night before a test.

Can I export my biology flashcards to Anki?

Yes, export to Anki is included with the Plus plan at $39/year or $7.99/month. The free plan lets you study in the browser without exports.

Can I get a ready-made set for biology unit 3 and 4?

DeckOwl does not provide shared or ready-made sets. It creates flashcards from the notes, slides or images you upload, so the cards reflect your own course material.
