Q

Pyruvate Oxidation Inputs?

A

pyruvate, coA, NAD+

17
Q

Pyruvate oxydation outputs?

A

co2, NADH, Acetyl Coa

18
Q

Citric acid cycle inputs?

A

Acetyl-coa, NAD+, ADP+Pi, FAD

19
Q

Citric acid cycle outputs?

A

NADH, co2, ATP, FADH2

20
Q

How many turns of the krebs cycle must occur for each molecule that undergoes respiration?

A

2

21
Q

Where does Citric acid cycle occur?

A

mitochondrial matrix

22
Q

net gain per glucose molecule?

A

2 ATP. 6NADH. 2 FADH2

23
Q

what is glycosis and krebs cycle?

A

substrate level phosphorylation

24
Q

What are the two parts of oxidative phosphorylation?

A

Electron transport chain and chemiosmosis

25
Q

ETC breakdown:

A

happens in inner mitochondiral matrix, H+ gets pumped across membrane, oxygen is the final electron acceptor

26
Q

As electrons move through the ETC, proton pumps move —- across the inner mitochondrial membrane?

A

h+

27
Q

the —- controls the fall of electrons from food to 02

A

electron transport chain

28
Q

Chemiosmosis breakdown:

A

H+ ions diffuse thru ATP synthase, ADP is bonded w Pi, 26-28 atp get produced

29
Q

Whats the process where h+ moves down a electromechanical gradient across a membrane?

A

chemiosmosis

30
Q

H+ perfroms work using

A

Atp synthase

31
Q

innermembrane space:

A

low ph, high h+ concentration

32
Q

matrix:

A

high ph, low h+ concentration

33
Q

fermentation procdues —-

A

ethanol or lactaid, co2

34
Q

does fermentations need o2? fermentation is assosicated with?

A

yes. glycolysis
