Sample item

Where does beta-oxidation of fatty acids occur primarily?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Mitochondrial matrix

The core Lipid metabolism principle identifies Mitochondrial matrix as the best answer because it most directly explains the biochemical pathway or tissue response described in the stem.

Option by option

  • A. Nucleus

    Nucleus does not match the stated lipid metabolism mechanism.

  • B. Golgi apparatus

    Golgi apparatus is relevant in another context but is not the best answer here.

  • C. Mitochondrial matrix (correct)

    Correct. Mitochondrial matrix is supported by the key clue given.

  • D. Lysosome

    Lysosome does not account for the central finding in this sample.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Lipid metabolism?

Build one table of enzyme deficiency, disease, inheritance and key finding, then revise it by spaced recall. Then use the flashcards and the other Biochemistry questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
