AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Pyruvate is a 3 (three)-carbon molecule.
This is a direct factual recall question. Pyruvate (CH₃COCOO⁻) is produced during glycolysis when a 6-carbon glucose molecule is split into two 3-carbon pyruvate molecules. Just write "3" or "three" — one word/number is sufficient for 1 mark.
