lyase
What type of enzyme is pyruvate kinase
Isomerase
What are the three fates of pyruvate?
In the presence of oxygen - Acetyl CoA (cellular respiration)
Without the presence of oxygen - Ethanol or lactate (fermentation)
Two phases of glycolysis?
Energy investment and energy generation
What type of phosphorylation occurs in glycolysis?
substrate level phosphorylation
Which two steps REQUIRE ATP?
Glucose -> Glucose 6 phosphate (Step 1)
Fructose 6 phosphate -> fructose 1,6 bisphosphate (Step 3)
Which stage generates NADH?
(Step 6) Glyceraldehyde 3 phosphate -> 1,3-bisphosphoglycerate
Which stages generate ATP?
(Step 7 and 10)
