Sample item

What organelle produces most cellular ATP by oxidative phosphorylation?

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

The answer and the reasoning

B. Mitochondrion

The core Cell physiology relationship supports Mitochondrion; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Golgi apparatus

    Golgi apparatus does not fulfill the structural or functional role requested.

  • B. Mitochondrion (correct)

    Correct. Mitochondrion is directly supported by the central clue.

  • C. Nucleus

    Nucleus is not consistent with the key finding in the stem.

  • D. Lysosome

    Lysosome is associated with a different cell physiology relationship.

Questions about this Physiology question

What is the answer to this Physiology question?

The best answer is B, Mitochondrion. The core Cell physiology relationship supports Mitochondrion; it is the response that directly accounts for the structural location or physiological change described.

Why is "Golgi apparatus" not the answer?

Golgi apparatus does not fulfill the structural or functional role requested.

Why is "Nucleus" not the answer?

Nucleus is not consistent with the key finding in the stem.

Why is "Lysosome" not the answer?

Lysosome is associated with a different cell physiology relationship.

What concept does this question test?

It tests Cell physiology in Physiology. The correct option holds because: Correct. Mitochondrion is directly supported by the central clue.

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 Cell physiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology 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.
