1:The reaction shown below is a/an ______________ reaction.

CH3COOH → CH3CHO

Oxidation

Reduction

2:The reactions converting glucose into CO2 taken together are _____ and ______:

Anabolic; require energy

Anabolic; release energy

Catabolic; require energy

Catabolic; release energy

3:Each of the following is a high-energy product of glycolysis. From which of these can anaerobic organisms harvest the stored energy? I.e. Which of these is/are useful to an anaerobe?

ATP

NADH

Pyruvate

All of the above

4:Assuming glucose is available and ATP levels are not too high, Glycolysis is active:

in anaerobic species

in aerobic species when O2 is available

in aerobic species when O2 is NOT available

All of the above

5:What product(s) is/are common to two of the reactions of the Citric Acid Cycle and the Pyruvate Dehydrogenase reaction?

ATP and NADH

ATP and CO2

NADH only

Both CO2 and NADH

ATP, NADH, and CO2

6:Which of the following is NOT a product of the Citric Acid Cycle?

Citric acid

CO2

NADH

FADH2

All of the above are products

7:What do glycolysis and the Citric Acid Cycle have in common?

They both involve oxidation of glucose.

They both occur in the cytoplasm.

They both produce CO2

They both produce ATP and NADH

8:Pyrimidines are synthesized through a long series of reactions beginning with the amino acid aspartate. The ribonucleotide CTP is one of the final compounds in this reaction pathway, and when the cell has enough CTP, it binds to and inhibits the enzyme that catalyzes the first reaction in the pathway, aspartate transcarbamoylase (ATCase). This is most likely an example of:

Competitive inhibition

Allosteric activation

Allosteric inhibition

Direct feedback inhibition

End-product inhibition

Both allosteric inhibition and end-product inhibition

Both competitive inhibition and direct feedback inhibition
