exam 1 electron transport system Flashcards
in aerobic metabolism we transfer electrons from NADH and FADH2 to what?
oxygen
in aerobic metabolism, oxygen is the final electron acceptor and in its reduction we make?
ATP
where does the electron transport system ETS take place?
inner mitochondrial membrane
what is the purpose of the ETS?
a mitochondrial mechanism that creates ATP by passing electrons along a system of carriers
in ETS, ATP is created by using?
the proton gradient
what is the source of electrons in the ETS?
macronutrient oxidation
the inner membrane of the ETS is impermeable to?
most small ions and small molecules
what allows molecules to transport into the inner membrane?
specialized carriers
the inner membrane of the mitochondria is rich in?
integral proteins
ETS coupled with the synthesis of ATP =
oxidative phosphorylation
in ETS, electrons are passed along carriers to create a?
proton gradient in the inter membrane space
what is the job of the 5 complexes of the ETS?
1-4 transfer electrons
5 catalyzes ATP synthesis
what is the name of complex 1?
NADH hydrogenase
what is the name of complex 2?
succinate dehydrogenase
what is the name of complex 3?
cytochrome reductase (bc1)
