lesson 9 Flashcards
one glucose molecule has been oxidized to
6 CO2
4 ATP
10 NADH
2 FADH2
oxidative phosphorylation
produces majority of ATP derived from glucose oxidaition
electron ransport chain
allows for the stepwise extraction of energy as electrons are passed from one component to the next
-energy-depleted electrons are eventually transferred to a final acceptor
electron energy is converted to ATP after the ETC
etc
3 transmembrane enzyme complexes harvest some energy from electrons and pass lower energy electrons onward
complexes use energy harvested form electrons to pump protons from matrix to intermembrane space
chemiosmosis
the proton gradient represent spotential energy
ATP synthase uses energy released by movement of protons to synthsize ATP from ADP+ Pi
anaerobic respiration
inorganic mocleules (not O2) used as final electron acceptor
free enrgy released and ATP is less than with O2
ex: methanogens
fermentation
glycolysis is only source of ATP
use of organic molecule as final electron acceptor
reduces organic molecules in order to regenerate NAD+
ex: lactic acid fermentation
