Lec 16 - Oxidative Phosphorylation

Question 1

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

Answer 1

matrix, intermembrane space

Question 2

heme has a blank ring which absorbs light

Answer 2

porphyrin ring

Question 3

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

Answer 3

succinate coA, glycine

Question 4

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

Answer 4

45, FMN, Fe-S

Question 5

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

Answer 5

4, Fe-S, succinate dehydrogenase

Question 6

complex 3 has blank proteins and uses blank as electron carriers

Answer 6

cytochrome, hemes

Question 7

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

Answer 7

cytochrome, heme, high

Question 8

complexes of the ETC

Answer 8

1-4

Question 9

complex that does oxidative phosphorylation

Answer 9

only 5!

Question 10

nad+ has a blank affinity for oxygen

Answer 10

low

Question 11

Proton motive force is converted to atp via this complex

Answer 11

5

Question 12

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

Answer 12

closed, open

Question 13

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

Answer 13

atp

Question 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

Answer 14

regulator, substrate

Question 15

there is blank between ETC and oxidative phosphorylation

Answer 15

coupling

Question 16

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

Answer 16

3 atp, 42%

Question 17

carbon monoxide prevents the oxidation of blank

Answer 17

cytochrome

Question 18

uncoupler of ETC and oxidative phosphorylation

Answer 18

dinitrophenol

Question 19

adp is a potent stimulator of blank

Answer 19

complex 5

Question 20

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

Answer 20

1-4
