Flashcards in Lec 16 - Oxidative Phosphorylation Deck (20):
1

proton flow goes across the inner mitochondrial membrane from blank to blank

matrix, intermembrane space

2

heme has a blank ring which absorbs light

porphyrin ring

3

in order to produce heme. 8 blank and blank are needed

succinate coA, glycine

4

complex 1 has blank polypeptides and these two types of electron carriers

45, FMN, Fe-S

5

complex 2 has blank polypeptides and has blank as a carrier but is insoluble and uses this enzyme

4, Fe-S, succinate dehydrogenase

6

complex 3 has blank proteins and uses blank as electron carriers

cytochrome, hemes

7

complex 4 has blank proteins, uses these as electron carriers and has a blank affinity for oxygen as the final electron acceptor

cytochrome, heme, high

8

complexes of the ETC

1-4

9

complex that does oxidative phosphorylation

only 5!

10

nad+ has a blank affinity for oxygen

low

11

Proton motive force is converted to atp via this complex

5

12

complex 5 has a membrane protein channel called F0 that is blank in the resting state and blank in the exertion state

closed, open

13

when F0 is open, the F1 (atp synthesis) is used to make blank

atp

14

adp is both a blank and blank because adp dissipates (collapses) proton gradient during exertion but at rest the proton gradient feedback inhibits the electron flow

regulator, substrate

15

there is blank between ETC and oxidative phosphorylation

coupling

16

each nadh results in about blank atp via the ETC which is blank percent efficient

3 atp, 42%

17

carbon monoxide prevents the oxidation of blank

cytochrome

18

uncoupler of ETC and oxidative phosphorylation

dinitrophenol

19

adp is a potent stimulator of blank

complex 5

20

electron flow goes along the inner mitochondrial membrane from blank to blank

1-4
