Question 1: Acetyl CoA Formation net ouput

Answer:

Acetyl CoA Carbon Dioxide NADH

Question 2: Pyruvate oxidized to

Answer:

CO2

Question 3: Glycolosis net ouput

Answer:

Pysruvate atp nadh

Question 4: FAD reduced to

Answer:

FADH2

Question 5: How many carbons in citrate and isocitrate

Answer:

6 Question 6: In glycolysis, the carbon-containing compound that functions as the electron donor is

Answer:

glucose

Question 7: Oxidative phosphorylation happens

Answer:

in inner mitochondrial membrane

Question 8: Glycolosis net input

Answer:

glucose nad adp Question 9: Suppose that a cell's demand for ATP suddenly exceeds its supply of ATP from cellular respiration, Which statement correctly describes how this increased demand would lead to an increased rate of ATP production?

Answer:

ATP levels would fall at first, decreasing the inhibition of PFK and increasing the rate of ATP production Question 10: Why is the citric acid cycle a cyclic pathway rather than a linear pathway?

Answer:

It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA

Question 11: Citric Acid Cycle net input

Answer:

NAD acetyl CoA ADP

Question 12: NAD+ is the compound that functions as the electron acceptor

Answer:

in glycolysis

Question 13: Once the electron donor in glycolysis gives up its electrons, it is oxidized to a compound called

Answer:

pyruvate

Question 14: Acetyl CoA formation happens

Answer:

in mitochondrial matrix

Question 15: Acetyl CoA Formation net input

Answer:

Pyrucate NAD Coenzyme A Question 16: How would anaerobic conditions (when no O2 is present) affect the rate of electron transport and ATP production during oxidative phosphorylation? (Note that you should not consider the effect on ATP synthesis in glycolysis or the citric acid cycle)

Answer:

Both electron transport and ATP synthesis would stop

Question 17: Critic acid cycle happens in

Answer:

mitochondrial matrix

Question 18: Oxidative Phosphorylation net input

Answer:

NADH Oxygen ADP Question 19: When a compound donates (loses) electrons, that compound becomes oxidized

Answer:

Such a compound is often referred to as an electron donor Question 20: Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions?

Answer:

pyruvate, ATP, and NADH

Question 21: Remains the same for gramicin

Answer:

rate of oxygen uptake, proton pumping rate, e- transport rate

Question 22: Oxidative net output

Answer:

ATP NAD Water

Question 23: Oxidative not input or output

Answer:

Glucose carbon dioxide acetyl CoA coenzyme A pyruvate

Question 24: How many carbons in alpha ketoglutarate

Answer:

5

Question 25: Citric Acid Cycle net output

Answer:

Carbon Dioxide ATP NADH coenzyme A Question 26: NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain, The electrons ultimately reduce O2 to water in the final step of electron transport, the amount of ATP made by electrons from an NADH molecule is greate

Answer:

Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor

Question 27: How many carbons in sussinyl CoA, succinate, oxaloacetate

Answer:

6

Question 28: Nad reduced to

Answer:

NADH
