Sample item

What is the main role of lipoprotein lipase?

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

The answer and the reasoning

C. Hydrolyse triglycerides in circulating lipoproteins

Lipoprotein lipase hydrolyses triglycerides in chylomicrons and VLDL, allowing fatty acids to enter muscle and adipose tissue.

Option by option

  • A. Break down DNA bases

    DNA base breakdown is unrelated.

  • B. Synthesize cholesterol in the nucleus

    Cholesterol synthesis uses cytosolic and ER enzymes.

  • C. Hydrolyse triglycerides in circulating lipoproteins (correct)

    Correct: it releases fatty acids from circulating triglycerides.

  • D. Convert ammonia to urea

    Urea synthesis occurs through the urea cycle.

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.
