  • PDF, Word, PowerPoint, Excel and text files
  • Up to 5 photos per upload, including scans
  • Drag and drop on Mac, Windows and the web

Practice questions that show their working

Every question comes with an explanation and the line from your notes it's based on, so you can check exactly where the answer came from.

  • Easy, medium and hard questions
  • An explanation for every answer, including wrong ones
  • See your accuracy at the end and try again

Pyruvate then moves into the mitochondrion. The citric acid cycle occurs in the matrix of the mitochondrion and releases carbon dioxide.
Question 4 of 10Medium

Tap another answer to see what happens when you get it wrong.

Correct. Glycolysis happens in the cytoplasm. Pyruvate then moves into the mitochondrion, and the cycle runs in its matrix.

Flashcards, made for you

Flip through the key ideas when you have five minutes. The back of each card has the explanation and where it came from in your notes.

Study notes you can read in minutes

Teach Back

If you can explain it, you know it

Pick a topic, or let koori pick one for you, and explain it out loud for up to three minutes. koori compares your explanation with your notes and tells you what you got right, what you missed and what to fix.
