Chapter 13: glucose metabolism Flashcards
Glycolysis: definition and phases
- conversion of 1 glucose (6-C) to 2 pyrufate (3-C)
- 10 reactions divided inot 2 phases
- 1st. phase: preperatory of investment phase
- 2nd phase: recovery or payoff phase
- the free energy released is “captured” in the form of ATP and NADH
Meaning of “preparatory or investment phase”
Meaning of “recovery or pay-off phase”
