Sample question
Lecture 6 · Cellular respiration
Question 3 of 10
Which organelle produces most of a cell’s ATP?
- ANucleus
- BMitochondrion
- CRibosome
- DGolgi apparatus
Correct!
Mitochondria use cellular respiration to convert energy from nutrients into ATP.
Most of the cell’s ATP is generated by oxidative phosphorylation in mitochondria.
Why this question counts
Wrong answers you’d actually consider. Every distractor is a real organelle from the same lecture, so guessing does not work.
A reason, not just a verdict. Each answer explains why it is right, so a miss turns into something you learned.
Traceable to your material. Where a passage backs the answer, we quote it word for word from your own file.
