|
What are the three major processes of aerobic respiration?
|
After glycolysis, the major aerobic mechanisms of metabolism are: (1) TCA (2) Electron Transport (3) Oxidative Phosphorylation
|
|
|
Amphibolic and relation to TCA
|
The TCA has a role in catabolism and anabolism; oxidation of butrients (catabolic) but some molecules are beginning of biosynth pathways
|
|
|
Main fuels of TCA? From Where? Ultimate end?
|
Glucose from carbs; amino acids from proteins and fatty acids from lipids will be turned into CO2 and H20
|
|
|
Where are all of these mechanisms taking place?
|
Glycolysis in the cytosol and TCA in the mitochondrial matrix (innermost) [e/c those were intermediate E-acceptor is FAD....part of mitochondrial mem)
|
|
|
AT the end of one turn of the TCA... One acetyl-CoA yields...
|
2 molecules of CO2; 3NADH; GTP; FADH2
