- 1What is the start point for gluconeogenesis?Pyruvate
- 2What is formed from pyruvate?Oxaloacetate
ATP use
HCO3- added
Pyruvate Carboxylase - 3What is formed from oxaloacetate?phosphoenol pyruvate
GTP used
CO2 released
Phosphoenolpyruvatecarboxy Kinase - 4What is formed from phosphoenol pyruvate?2-phosphoglycerate
Enolase
H2O removed - 5What is formed from 2-phosphglycerate?3-phosphglycerate
phosphoglycerate mutase - 6What is formed from 3-phosphoglycerate?1,3-bisphosphoglycerate
ATP used
3-phosphoglyceratekinase - 7What is formed from 1,3-bisphosphoglycerate?Glyceraldehyde-3-phosphate
NADH used
Pi released
GAP dehydrogenase - 8What is formed from glyceraldehyde-3-phosphate?Fructose-1,6-bisphosphate
Aldolase - 9What is formed from fructose-1,6-bisphosphate?Fructose-6-phosphate
Addition of H2O
Pi removed
fructose-1,6-bisphosphotase - 10What is formed from fructose-6-phosphate?Glucose-6-phosphate
phosphohexose isomerase - 11What is formed from glucose-6-phosphate?Glucose
H2O added
Pi removed
Glucose-6-phosphotase - 12What can be the start for gluconeogenesis?Lactate
oxaloacetate
pyruvate
glycerol
alanine - 13What 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 - 14What is an essential requirement of glucose?Brain respiration - when depleted, organs convert lactic acid into glucose
- 15What occurs in long-term starvation?Brain must respire ketone bodies
Body convert proteins into glucose via amino acids in citric acid cycle
