ETC

Question 1

ATP synthase

Answer 1

Helps H get back since the cristae is impermeable. Phosphorylates 3 ADP to 3 ATP. Complex V, two,domains F1 F0
Reversible

Question 2

Which heme cannot be removed from protein even after unfolded

Answer 2

Heme C because it’s covalently bound to cytochrome C through thioester bonds to two Cys residues

Question 3

During the transfer of electrons to O2

Answer 3

The energy released is used to translocation protons across inner membrane

Question 4

F1

Answer 4

Domain in ATP synthese

Catalyze synthesis of ATP

Question 5

Inner mitochondrial membrane has a transporter for

Answer 5

ATP

Question 6

If ETC is operation the pH will be

Answer 6

pH in matrix will be higher than in inter membrane space

Question 7

Mitchell’s chemiosmotic hypothesis

Answer 7

Membrane impermeable to protons
Pumps protons out
Depends on ADP P
ATPase is reversible

Question 8

How many ATP per NAD

Answer 8

2.5

Question 9

Uncoupling of mitochondrial oxidative phosphorylation

Answer 9

Stops mitochondrial ATP formation but still consumes O2

Question 10

The proton motive force

Answer 10

Includes a pH gradient
Electrical potential gradient
Used of active transport
Synthesizes ATP
