metabolism
|
catabolism: breaking down, release of energy
anabolism: synthesis of molecules,requires energy |
|
|
options of energy conservation
(fermentation) |
leads to incomplete metabolism of pyruvic acid to organic end-pdts. very inefficient,oxidation is coupled to a pdt generated from the initial e- donor (substrate)
|
|
|
options of energy conservation
(respiration) |
leads to complete oxidation of pyruvic acid to CO2 and H2O. requires externally supplied e- acceptor, yields to other metabolic processes. (anaerobic respiration, photosynthesis,chemolithotrophy, proton motive force)
|
|
|
phosphorylation:ATP synthesis
(fermentation) |
ATP produced by substrate level phosphorylation and directly linked to catabolism of organic compound.
|
|
|
phosphorylation:ATP synthesis
(respiration) |
ATP is produced by oxidative phosphorylation at the expense of proton motive force
