Glycolysis WTF DOES THIS ENZYME DO?! Flashcards
Hexokinase
Glucose –> Glucose-6-Phosphate
Requires ATP & Mg2+
Phosphohexose-Isomerase
Glucose-6-Phosphate –> Fructose-6-Phosphate
Requires Mg2+
O attaches to C2 instead of C1
Pyranose –> Furanose
Phosphofructokinase-1 (PFK-1)
Fructose-6-Phosphate –> Fructose-1,6-Bisphosphate
Requires ATP & Mg2+
Adolase
Fructose-1,6-Bisphosphate –> Dihydroacetone Phosphate + Glyceraldehyde-3-Phosphate
Cleavage rxn.
Triose Phosphate Isomerase
Dihydroxyacetone Phosphate –> Glyceraldehyde-3-Phosphate
G3P needed to move on!
Glyceraldehyde-3-Phosphate Dehydrogenase
Glyceraldehyde-3-Phosphate + Inorganic Phosphate –> 1,3-Bisphoglycerate
Reduces NAD+ to NADH + H+
Phosphoglyceratekinase
1,3-Bisphoglycerate –> 3-Phosphoglycerate
Requires Mg2+
Phosphoglyceratemutase
3-Phosphoglycerate –> 2-Phosphoglycerate
Just changes Phosphate group position from C3 to C2
Enolase
2-Phosphoglycerate –> Phosphoenolpyruvate
Removes H2O, creates double bond
Pyruvatekinase
Phosphoenolpyruvate –> Pyruvate
Requires Mg2+ & K+
Makes ATP
