Sample item

Which hormone activates hormone-sensitive lipase in adipose tissue?

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

The answer and the reasoning

B. Epinephrine

Epinephrine stimulates lipolysis through cyclic AMP signalling, activating hormone-sensitive lipase and releasing fatty acids during fasting or stress.

Option by option

  • A. Insulin

    Insulin suppresses adipose lipolysis.

  • B. Epinephrine (correct)

    Correct: catecholamines mobilize adipose triglyceride stores.

  • C. Prolactin

    Prolactin has lactation-related actions.

  • D. Aldosterone

    Aldosterone regulates sodium balance.

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.
