Glycolysis Flashcards
what is another name for anaerobic glycolysis?
Ebden Meyerhoff Pathway
write the equation for the overall pathway of glycolysis
glucose -> 2 pyruvate + 2 ATP + 2 NADH + 2 H2O
what substance do RBC’s convert pyruvate into that is able to leave the cell?
lactate
write the equation for RBC’s and clearly label the enzyme that does this conversion
pyruvate + NADH -> lactate + NAD
(lactate dehydrogenase)
what do yeast convert pyruvate into?
CO2 + Alcohol (+NAD)
write the equation for yeast and clearly label the names of the enzymes that do this conversion
pyruvate + NADH +H -> CO2 + alcohol + NAD
(acetaldehyde / alcohol dehydrogenase)
Name the 3 stages of glycolysis
investment stage
splitting stage
yield stage
name the allosteric enzyme for glycolysis
phosphofructokinase
what hormone increases the function of the allosteric enzyme of glycolysis?
insulin
list the steps of the investment stage
glucose -> glucose 6P -> fructose 6P -> fructose 1,6 BP
what is the coenzyme for the step glucose -> glucose 6P?
ATP -> ADP
what is the coenzyme for fructose 6P -> fructose 1,6 BP?
ATP -> ADP
what is the enzyme that converts glucose -> glucose 6P?
hexokinase
what enzyme converts glucose 6P -> fructose 6P?
isomerase
what enzyme converts fructose 6P -> fructose 1,6 BP?
phosphofructokinase (allosteric)
name the steps of the splitting stage
fructose 1,6 BP -> DHAP
-> G3P
what enzyme splits fructose 1,6 BP into DHAP and G3P?
aldolase
what enzyme converts DHAP to G3P?
isomerase
what product of the splitting stage can enter the yield stage?
G3P
name the steps of the yield stage
G3P -> 1,3 BP glycerate -> 3 phosphoglycerate -> 2 phosphoglycerate -> phosphoenolpyruvate -> pyruvate
what are the coenzymes for glyceraldehyde 3P dehydrogenase?
NAD + Pi
what are the byproducts of the yield stage?
NADH
ATP
Water (H2O)
ATP
name the enzymes at the steps where ATP is produced
phosphoglycerate kinase
pyruvate kinase
what is the name of the enzyme that produces water as its coenzyme?
enolase
what is the coenzyme of pyruvate kinase?
ADP -> ATP
