Energy investment – Steps 1-3 – 2 ATP hydrolyzed to create fructose-1,6 bisphosphate Cleavage – Steps 4-5 – 6 carbon molecule broken into two 3 carbon molecules of carbon glyceraldehyde-3-phosphate glyceraldehyde-3-phosphate Energy liberation – Steps 6-10 – Two glyceraldehyde-3-phosphate molecules broken down into two Two pyruvate molecules producing 2 NADH and 4 ATP pyruvate Net yield in ATP of 2 Stage 2: Breakdown of pyruvate to an acetyl group In eukaryotes, pyruvate in In transported to the mitochondrial matrix matrix Broken down by pyruvate Broken dehydrogenase dehydrogenase Molecule of CO2 removed from each pyruvate each Remaining acetyl group Remaining attached to CoA to make acetyl CoA CoA 1 NADH is made for each NADH pyruvate pyruvate Stage 3: Citric acid cycle Stage Metabolic cycle – Particular molecules enter while other leave, involving a Particular series of organic molecules regenerated with each cycle series Acetyl is removed from Acetyl CoA and attached to Acetyl...
