Enzymes of glycolysis and gluconeogenesis

Hexokinase

glucose to glucose-6-phosphate

glucose-6-phosphatase

glucose-6-phosphate to glucose

Phosphoglucose isomerase

converts between glucose-6-phosphate and fructose-6-phosphate

phosphofructokinase

fructose-6-phosphate to fructose-1,6-biphosphate

fructose bisphosphatase

fructose-1,6-biphosphate to fructose-6-phosphate

aldolase

converts between fructose-1,6-biphosphate and (DHAP + GAP)

triose phosphate isomerase

converts between glyceraldehyde-3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP)

glyceraldehyde-3-phosphate dehydrogenase

converts between GAP and 1,3-Bisphosphoglycerate

phosphoglycerate kinase

converts between 1,3-Bisphosphoglycerate and 3-Phosphoglycerate

phosphoglycerate mutase

converts between 3-phosphoglycerate and 2-phosphoglycerate

enolase

converts between 2-phosphoglycerate and phosphoenolpyruvate

pyruvate kinase

phosphoenolpyruvate to pyruvate

pyruvate carboxylase

pyruvate to oxaloacetate

PEPCK

oxaloacetate to phosphoenolpyruvate

what steps/enzymes of glycolysis USE ATP

hexokinase + phosphofructokinase

what steps/enzymes of glycolysis PRODUCE ATP

phosphoglycerate kinase + pyruvate kinase

pyruvate carboxylase uses what in its reaction

ATP + CO2 → P_i + ADP

PEPCK uses what in its reaction

GTP → CO₂ + GDP

what enzymes of gluconeogenesis use water to produce inorganic phosphate

fructose bisphosphate + glucose-6-phosphatase

What does glyceraldehyde-3-phosphate dehydrogenase require for its gluconeogenesis reaction?

NADH + H⁺ → NAD⁺ + P_i
