Sample item

What reducing equivalent is generated by pentose phosphate pathway?

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

The answer and the reasoning

A. NADPH

This item reviews Pentose phosphate; NADPH is the best answer because it directly fits the mechanism or morphology described.

Option by option

  • A. NADPH (correct)

    Correct. NADPH is supported by the defining finding.

  • B. ATP only

    ATP only is plausible but is not the best fit here.

  • C. FADH2

    FADH2 does not match the key mechanism or pattern.

  • D. GTP only

    GTP only is not supported by the stated finding.
