Q

After the TRANSITION REACTION, where pyruvate is transformed to acetyl CoA, most of the energy from the original glucose molecule is…
A. used up in modifying pyruvate B. transferred to ADP, forming ATP C. transferred directly to ATP
D. stored in the acetyl CoA
E. storedintheNADHproduced

A

Stored in NADH because it is used later for ATP

Q

Is NADH produced in Krebs cycle? Is FADH produced? How many for both

A

Yes 6 for NADH and 2 for FADH

17
Q

Is ATP produced in Krebs

A

2

18
Q

Does Krebs produce any other molecules

A

No

19
Q

All together, how many total NADH and FADH2 energy carriers are produced by the end of G.T.C. and before E.?
A. 4 B. 8 C. 10 D. 12 E. 1

A

12 due to for NADH producing 2 during glycolysis 2 during transition reaction and 6 for Krebs. Then for FADH there is none produced for glycolysis/transition. There are 2 for Krebs

20
Q

At the end of the Citric Acid/Kreb’s Cycle, most of the energy that was originally in glucose is
A. used up in the splitting of glucose
B. transferred to ADP, forming ATP
C. transferred directly to ATP
D. storedintheAcetylCoA
E. stored in the NADH and FADH2 produced

A

E because the energy is stored there to be used for later

21
Q

Where was the
OXYGEN ATOM
in exhaled carbon dioxide just BEFORE it was part of carbon dioxide?

A

Oxygen gas

22
Q

What is the reason as to why energy can finally be transferred into ATP

A

electron transport chain

23
Q

What is the final electron acceptor and combines with hydrogen ions and electrons to produce water

A

Oxygen

24
Q

For every molecule of NADH how many ATP are made

A

3

25
Q

For every molecule of FADH how many ATP are made?

A

2

26
Q

Where does the electron transport chain take place?

A

In the mitochondria

27
Q

In the electron transport chain how many Co2 is produced?

A

0

28
Q

Does the electron transport chain have NADH / FADH

A

yes

29
Q

How many ATP does the electron transport chain produce?

A

34

30
Q

What key molecules does the electron transport chain produce?

A

Water

31
Q

In which cycle is co2 produced remember there’s two

A

The Krebs cycle, and the transition reaction

32
Q

In which processes are the small ENERGY CARRIERS NADH
made? FADH,?

A

Glycolysis, transition reaction, Krebs cycle

33
Q

What molecule was the final electron in the electron transport chain?

A

Oxygen

34
Q

In which processes is atp produced?

A

Glycolysis, Krebs cycle, electron transport chain

35
Q

How is combustion (e.g., burning gasoline,) similar to cellular respiration?

A

Both use oxygen and produce Co2

36
Q

A patient who has been poisoned arrives in the emergency room. The patient’s ATP levels are low and NADH levels are high. Which of the following cellular respiration processes is likely to be most affected?
A. citric acid/Krebs cycle
B. glycolysis
C. theelectrontransportchain&
chemiosmosis
D. transition reaction

A

C due to the low ATP the fact that NADH is high mean that glycolysis and the Krebs cycle is functioning proper
