cellular respiration Flashcards
mitochondria
site of aerobic cellular respiration
cristae
folds in the mitochondria
matrix
surrounds the cristae
cellular respiration
breakdown of glucose resulting in the release of energy, most lost as head, some is trapped in the form of ATP
aerobic cellular respiration
breakdown of glucose to simple inorganic compound in the prescence of oxygen
anaerobic cellular respiration
breakdown of glucose to simple inorganic compound in the absence of oxygen
how many ATPs does aerobic cellular respiration give off
28 of 30 ATP per glucose molecule
how many ATPs does anaerobiccellular respiration give off
2 ATP per glucose molecule
aerobic cellular respiration equation
C6H12O6 + 6O2 -(30 0r 32 ADP+PI, 30 or 32 ATP)- 6CO2 + 6H2O
anaerobic cellular respiration equation (lactic acid fermentation)
glucose -(2 ADP+Pi, 2 ATP)- lactic acid
anaerobic cellular respiration equation (alcoholic fermentation)
glucose -(2 ADP+Pi, 2 ATP)- ethanol + CO2
glycolysis
breakdown of glucose into 2 pyruvate
where does glycolysis occur and how many ATPs does it yield
in the cytosol, 2 ATPs per glucose split
glycolysis inputs
glucose, 2ADP+Pi, NAD+
glycolysis outputs
2 pyruvate, 2 ATP, NADH
where does the krebs cycle occur
matrix of the mitochondria
what is Krebs cycle
the breakdown of pyruvate into 3CO2 molecules
krebs cycle inputs
2 pyruvate, 2ADP+Pi, NAD+, FAD
krebs cycle outputs
2 ATP, 6CO2, NADH, FADH2
atps made in electron transport chain
26 or 28 atp per glucose
ETC inputs
6O2, 26 or 28 ADP+Pi, NADH, FADH2
ETC outputs
6H2O, 26 or 28 ATP, NAD+, FAD
where does the etc occur
in the cristae of the mitochondria
atp yield in the Krebs cycle
2 ATP per glucose split
