Glycolysis Flashcards

1
Q

Energy investments stages of glycolysis (5)

A
  1. glucose is phosphorylated to glucose-6-phosphate
  2. glucose-6-phosphate –> fructose-6-phosphate (isomerisation)
  3. add ATP = fructose-1,6-bisphosphate
  4. splits into G3P and DHAP
  5. DHAP converted to G3P

Q

Energy payoff steps of glycolysis (5)

A
  1. G3P + NAD+ + Pi –> 1,3-bisphosphoglycerate + NADH + H+
  2. 1,3-bisphosphoglycerate + ADP –> 3-phosphoglycerate + ATP
  3. 3-phosphoglycerate –> 2-phosphoglycerate
  4. 2-phosphoglycerate –> PEP + H2O
  5. PEP + ADP –> pyruvate +ATP
