In the absence of oxygen, the primary purpose of fermentation is to:
1. produce amino acids for protein synthesis
2. generate a proton gradient for ATP synthesis
3. oxidize glucose to generate reduce electron carriers
4. regenerate NAD+ from NADH allowing glycolysis to continue

During glycolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is 
1. transferred to ADP, forming ATP.
2. transferred directly to ATP.
3. retained in the pyruvate.
4. stored in the NADH produced.

ATP production during cellular respiration is controlled by allosteric inhibition. The control is the allosteric inhibition by ATP and citric acid of the enzyme that facilitates the formation of:

1. Glucose 6- phosphate from glucose
2. Fructose 1,6- bisphosphate from Fructose 6 - phosphate
3. Acetyl CoA from Pyruvic acid
4. Citric acid from Acetyl CoA and Oxaloacetic acid
