Sample item

What is the main metabolic purpose of glycolysis?

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

The answer and the reasoning

B. Convert glucose to pyruvate while generating ATP

Glycolysis converts glucose to pyruvate in the cytosol and captures energy as ATP and NADH without requiring oxygen directly.

Option by option

  • A. Convert fatty acids directly to ketones only

    Ketogenesis is a separate hepatic pathway.

  • B. Convert glucose to pyruvate while generating ATP (correct)

    Correct: glycolysis makes pyruvate and energy.

  • C. Break down haemoglobin

    Haemoglobin breakdown is not glycolysis.

  • D. Synthesize urea in the liver

    The urea cycle disposes of nitrogen.
