Question

If an inhibitor that blocked the oxidation of NADH was added to a strict aerobe bacterial culture, which two statements would be correct?

fermentation would begin and allow for oxidation of NADH

ATP energy created by oxidative phosphorylation through respiration would cease

adding extra oxygen to the culture could overcome the effects of the inhibitor

an acidic waste product would begin to build up in the culture

glycolysis and TCA cycle would eventually cease running due to lack of electron acceptors

NAD+ would begin to build up in the cell

A

fermentation would begin and allow for oxidation of NADH

B

ATP energy created by oxidative phosphorylation through respiration would cease

C

adding extra oxygen to the culture could overcome the effects of the inhibitor

D

an acidic waste product would begin to build up in the culture

E

glycolysis and TCA cycle would eventually cease running due to lack of electron acceptors

F

NAD+ would begin to build up in the cell

Explanation / Answer

B) ATP energy created by oxidative phosphorylation through respiration would cease, and

E) glycolysis and TCA cycle would eventually cease running due to lack of electron acceptors, are the two correct possibilities, when an inhibitor blockes the oxidation of NADH was added to a strict aerobe bacterial culture.
