Across
- 5. Allosteric activator of PFK-1; regulates glycolysis vs. gluconeogenesis
Down
- 1. Moves 2-carbon units; needs TPP (thiamine)
- 2. Splits fructose-1-P into DHAP + glyceraldehyde
- 3. PPP rate-limiting enzyme; inhibited by NADPH
- 4. Type of reaction; refill TCA cycle intermediates (e.g., pyruvate → OAA)
