Cheat Sheet
- ATP Investment and Net Yield -
Glycolysis invests 2 ATP in the energy”investment phase (steps 1 - 3) and produces 4 ATP and 2 NADH in the payoff phase (steps 7 - 10), yielding a net of 2 ATP and 2 NADH per glucose. Remember this balance when you tackle glycolysis quiz or practice questions to avoid mixing up totals. Use the equation: glucose + 2 ADP + 2 Pi + 2 NAD+ → 2 pyruvate + 2 ATP + 2 NADH + 2 H+ to solidify your understanding.
- Regulatory Enzymes: PFK-1, Hexokinase & Pyruvate Kinase -
Phosphofructokinase-1 is the pathway's key rate-limiting step, allosterically inhibited by ATP and activated by AMP and fructose-2,6-bisphosphate. Hexokinase traps glucose in the cell, and pyruvate kinase catalyzes the final ATP”generating step. Mastering these control points boosts your score on any glycolysis pathway quiz or glycolysis game challenge.
- NADH Formation and Anaerobic Regeneration -
During step 6, glyceraldehyde-3-phosphate dehydrogenase reduces NAD+ to NADH; under anaerobic conditions, lactate dehydrogenase regenerates NAD+ by converting pyruvate to lactate. This balance is crucial for sustained glycolytic flux and a common focus of glycolysis practice questions. Recall that 2 NADH per glucose are produced, linking energy yield to redox balance.
- Substrate Sequence Mnemonic -
Use "Hungry Peter Pan And The Growling Pink Panther Ate Eight Pickles" to recall Hexokinase, Phosphoglucose isomerase, Phosphofructokinase, Aldolase, Triose phosphate isomerase, Glyceraldehyde-3-phosphate dehydrogenase, Phosphoglycerate kinase, Phosphoglycerate mutase, Enolase, Pyruvate kinase. Mnemonics like this sharpen recall in the remember steps of glycolysis quiz or during fast-paced glycolysis practice questions. Keep it handy to breeze through each enzyme and order.
- High-Energy Intermediates Drive ATP Synthesis -
1,3-Bisphosphoglycerate and phosphoenolpyruvate are high-energy intermediates that donate phosphates to ADP via substrate-level phosphorylation. Recognizing these intermediates is key to understanding how glycolysis generates ATP and acing detailed items in your glycolysis quiz. Think of them as the "energy currency" coins you spend to power the cell.
