Question
Question #1:Oxygen, as part of the ETC, is responsible for regeneration of FAD and NADP+, which are required to keep the oxidative TCA cycle functioning
a.) True
b.) False
Question #2:Conversion of oxaloacetate + acetyl-CoA to citrate:
a.) requires NAD+
b.) requires FAD
c.) produces carbon dioxide
d.) utilizes GTP as an energy source

a.) 1
b.) 2
c.) 3
d.) 4
e.) 6
Question #5:How many NADPH molecules are produced by pyruvate dehydrogenase and the TCA cycle per molecule of phosphoenolpyruvate that goes through glycolysis, pyruvate dehydrogenase, and the TCA cycle? a.)3
b.) 4
c.) 6
d.) 8
e.) 0
Explanation / Answer
Q 1). Oxygen, as part of the ETC, is responsible for regeneration of FAD and NADP+, which are required to keep the oxidative TCA cycle functioning ----------------> TRUE
Q 2). e.) produces free CoA-SH
Conversion of oxaloacetate + acetyl-CoA (in the presence of water) to citrate produces free CoA-SH and proton.
Q 3). The TCA cycle itself is an anaerobic process that requires FAD and NAD+ but does not directly require oxygen. ----------> TRUE.
The TCA cycle do not directly require oxygen, but it is considered as aerobic process.
