Metabolism Flashcards
derived from breakdown of carbs, lipids and proteins
catabolism
ATP derived is used in synthesis of cellular components
anabolism
Glycolysis:
whats the net gains?
- 1 glucose to 2 molecules of pyruvate
- 2 ATP via substrate level phosphorylation
- 2 NADH
TCA: whats the net gains?
- pyruvic acid completely oxidized to water and CO2
- 2 ATP
- 6 NADH
- 2 FADH2
What is the final electron acceptor in the ETC?
oxygen
chemoiosmotic theory?
ATP is synthesized as result of proton motive force generated by passing electrons along chain
oxidative phosphorylation?
the use of the reducing power of NADH, FADH2 to synthesize ATP
Aerobic respiration
the process of transferring electrons from NADH and FADH2 to oxygen
In the absence of O2 if electrons are transferred to an inorganic terminal electron acceptor, such as sulfur, this process is known as
anaerobic respiration
In the absence of O2 if electrons are transferred to organic terminal electron acceptor this process is known as
fermentation, used by organisms that can’t respire
ATP yield from aerobic respiration?
38 ATP
ATP yield from anaerobic respiration?
30 or less ATP
ATP yield from fermentation?
2-4 ATP
