Sample item

What is the major role of HDL in lipid transport?

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

The answer and the reasoning

C. Reverse cholesterol transport

The defining Lipid metabolism relationship supports Reverse cholesterol transport; it is the option that most directly explains the biochemical pathway or pathological process in the stem.

Option by option

  • A. Transport bilirubin only

    Transport bilirubin only does not account for the central finding in this item.

  • B. Carry oxygen

    Carry oxygen is relevant in a different context but is not supported here.

  • C. Reverse cholesterol transport (correct)

    Correct. Reverse cholesterol transport is the appropriate conclusion from the key feature.

  • D. Deliver triglycerides from diet

    Deliver triglycerides from diet does not match the stated lipid metabolism mechanism.
