5.3 Respiration Flashcards
stages of aerobic respiration
- glycolysis
- link reaction
- krebs cycle
- electron transport chain (E.T.C.)
stages of anaerobic respiration
- glycolysis
- fermentation
glycolysis: inputs
glucose, ADP, NAD+
link reaction: inputs
pyruvate, CoA, NAD+
krebs cycle: inputs
acetyl-CoA, NAD+, ADP, FAD
E.T.C.: inputs
NADH, FADH2, H+, O2, ADP
fermentation: inputs
pyruvate, NADH
glycolysis: outputs
pyruvate, ATP, NADH
link reaction: outputs
acetyl-CoA, CO2, NADH
krebs cycles: outputs
CO2, NADH, ATP, FADH2
E.T.C.: outputs
NAD+, FAD, H2O, ATP
fermentation: outputs
alcoholic fermentaion: ethanol, CO2, NAD+
lactic acid fermentation: lactic acid, NAD+
glycolysis: location
cytoplasm
link reaction: location
mitochondrion
krebs cycle: location
mitochondrion
E.T.C: location
inner membrane of the mitochondrion
fermentation: location
cytoplasm
chemical reaction
C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O
~29 ADP + ~29 P -> ~29 ATP + ~29 H20
respiration with oxygen vs respiration without oxygen
with oxygen: link reaction, krebs cycle, E.T.C.; ~34 ATP/glucose
without oxygen: fermentation; 2 ATP/glucose
both: glycolysis
