| Question | Answer |
| What is the start point for gluconeogenesis? | Pyruvate |
| What is formed from pyruvate? | Oxaloacetate ATP use HCO3- added Pyruvate Carboxylase |
| What is formed from oxaloacetate? | phosphoenol pyruvate GTP used CO2 released Phosphoenolpyruvatecarboxy Kinase |
| What is formed from phosphoenol pyruvate? | 2-phosphoglycerate Enolase H2O removed |
| What is formed from 2-phosphglycerate? | 3-phosphglycerate phosphoglycerate mutase |
| What is formed from 3-phosphoglycerate? | 1,3-bisphosphoglycerate ATP used 3-phosphoglyceratekinase |
| What is formed from 1,3-bisphosphoglycerate? | Glyceraldehyde-3-phosphate NADH used Pi released GAP dehydrogenase |
| What is formed from glyceraldehyde-3-phosphate? | Fructose-1,6-bisphosphate Aldolase |
| What is formed from fructose-1,6-bisphosphate? | Fructose-6-phosphate Addition of H2O Pi removed fructose-1,6-bisphosphotase |
| What is formed from fructose-6-phosphate? | Glucose-6-phosphate phosphohexose isomerase |
| What is formed from glucose-6-phosphate? | Glucose H2O added Pi removed Glucose-6-phosphotase |
| What can be the start for gluconeogenesis? | Lactate oxaloacetate pyruvate glycerol alanine |
| What is the Cori Cycle? | Muscle tissue generates lactic acid. If not removed, causes acidosis Converted back to glucose in liver, then returned to muscle and stored as glycogen |
| What is an essential requirement of glucose? | Brain respiration - when depleted, organs convert lactic acid into glucose |
| What occurs in long-term starvation? | Brain must respire ketone bodies Body convert proteins into glucose via amino acids in citric acid cycle |
