Sample item

What is the key metabolic effect of insulin after a carbohydrate-rich meal?

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

The answer and the reasoning

B. Promote glucose uptake and storage in insulin-sensitive tissues

Insulin promotes glucose uptake in muscle and adipose tissue, glycogen synthesis, lipogenesis, and suppression of hepatic glucose output after feeding.

Option by option

  • A. Raise blood glucose through glycogenolysis

    Glycogenolysis raises glucose during fasting signals.

  • B. Promote glucose uptake and storage in insulin-sensitive tissues (correct)

    Correct: insulin supports nutrient use and storage after meals.

  • C. Increase hepatic ketone production

    Ketone production rises when insulin is deficient.

  • D. Stimulate lipolysis in adipose tissue

    Insulin suppresses rather than stimulates adipose lipolysis.

Questions about this Physiology question

What is the answer to this Physiology question?

The best answer is B, Promote glucose uptake and storage in insulin-sensitive tissues. Insulin promotes glucose uptake in muscle and adipose tissue, glycogen synthesis, lipogenesis, and suppression of hepatic glucose output after feeding.

Why is "Raise blood glucose through glycogenolysis" not the answer?

Glycogenolysis raises glucose during fasting signals.

Why is "Increase hepatic ketone production" not the answer?

Ketone production rises when insulin is deficient.

Why is "Stimulate lipolysis in adipose tissue" not the answer?

Insulin suppresses rather than stimulates adipose lipolysis.

What concept does this question test?

It tests Endocrine physiology in Physiology. The correct option holds because: Correct: insulin supports nutrient use and storage after meals.

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 Endocrine 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.
