Question 3 of 10

Where in the cell does the Krebs cycle take place?

A. Cytoplasm
B. Mitochondrial matrixCorrect
C. Inner mitochondrial membrane
D. Nucleus

The Krebs cycle runs in the matrix, the space inside the inner membrane. The electron transport chain is the one on the inner membrane, which is why C is a common mix-up.

How it works

1

Upload what your professor gave you

Lecture slides, a study guide, or your own notes.

2

Gus writes the questions

Only from your material, so you study what's on your exam, not the whole textbook.

3

Learn from every miss

Each answer explains why, and shows the slide it came from.

Questions

Is it really free?

Yes. 10 questions per upload, no account, no card. An account saves your questions and makes flashcards.

Can I make a practice test from a PowerPoint?

Yes. Upload the .pptx file as it is. PDFs of slides, Word documents and photos of handwritten notes work too.

Are the questions like real exam questions?

They come only from what you upload, and you pick the difficulty. When your file has slides or pages, each question shows the one it came from so you can check it.

Can I use my lecture recording instead?

Inside Gus, yes. Record the lecture and Gus makes the quiz from what your professor actually said.

Do you keep my slides?

No. The file is sent to an AI model to write the questions and deleted as soon as your test is ready. Nothing is saved, and there is no account to save it to.
