biol 151 ETC

oxidative phosphorylation

QuestionAnswer
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
