Fermentation & aerobic respiration Flashcards
What is glycolysis?
an anaerobic process that consumes glucose & produces 2 net ATP per glucose molecule oxidized
What are the stages of glycolysis?
stage 1- consumes energy
stage 2- yields energy
What are the biochemical steps for fermentation?
- glycolysis
2.oxidation of NADH->NAD+
What is the ATP yield of fermentation?
2 ATP
What are the waste products of fermentation?
acids, gases, & alcohol
What is the final e- receptor of fermentation?
pyruvate or other organic molecules
What is the required environment for fermentation?
aerobic or anaerobic
Explain bacteroids
gram negative, anaerobic, ferment wide range of sugars from plants, major inhabitant of human intestine, can cause infections if they escape intestine
What are the biochemical steps of aerobic respiration?
- glycolysis
- pyruvate oxidation
- Kreb cycle
- electron transplant chain (proton motive force)
- oxidative phosphorylation
What is the ATP yield of aerobic respiration?
38 ATP in bacteria
What are the waste products of aerobic respiration?
CO2 & H2O
What is the final e- receptor in aerobic respiration?
O2
What is the required environment for aerobic respiration?
aerobic environment
