biol 151 ETC
oxidative phosphorylation
Question | Answer |
---|---|
all reactions before this produce.... | CO2, ATP, electron carriers (NADH and FADH2) |
why is it called oxidative phosphorlyation? | oxygen is involved and bonds together to produce water |
electron transport chain takes place in the.... | inner membrane between matrix and intermembrane space |
the only thing that unites the complexes is... | that energy (electrons) flow between them |
complex 1 contains... | NADH dehydrogenase, which oxidizes NADH in NAD to harvest electrons |
which can pump H+ protons? | 1, 3, 4 |
what is ubiquinone? | moves electrons from 1 and 2 to 3 |
complex 2 contains... | enzymes: succinate dehydrogenase, which oxidizes FADH into FAD |
complex 3 moves electrons... | from ubiquinone to cytochrome c |
what are the functions of everything here??? | moves electrons to generate the proton gradient so we can make ATP! |
cytochrome c... | moves electrons from 3 to 4 |
ubiquinone is unique because... | lipid soluble, freely moves through hydrophobic membrane core |
how many electrons to reduce oxygen to make water? | 4 |
ETC is inhibited by... | cyanide, nitric oxide, molecular oxygen |
inner membrane is impermeable to... | H+ ions |
what is the terminal electron receptor? | oxygen |
