Sample item

What is the end product of anaerobic glycolysis in muscle?

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

The answer and the reasoning

D. Lactate

The defining Carbohydrate metabolism relationship supports Lactate; it is the option that most directly explains the biochemical pathway or pathological process in the stem.

Option by option

  • A. Urea

    Urea does not account for the central finding in this item.

  • B. Acetyl-CoA

    Acetyl-CoA does not match the stated carbohydrate metabolism mechanism.

  • C. Oxaloacetate

    Oxaloacetate is relevant in a different context but is not supported here.

  • D. Lactate (correct)

    Correct. Lactate is the appropriate conclusion from the key feature.
