Question

What conclusions can be made or what is the truth if the sentence is false?

1) A lack of oxygen causes cells to convert pyruvate to lactate to regenerate the NAD+ required for Glycolysis.

2) I purify protein “X” from a certain species of frog. I then purify protein “Y” from another frog species. These two proteins appear to have different masses, and charges. However, after treating the purified proteins with Glycosidase, they end up having identical masses and charges. Sequencing shows that X and Y have identical amino acid sequences.

3) Gluconeogenesis is upregulated during prolonged exercise since blood sugar levels drop

4) A substrate cycle between DHAP and GA3-P might be used by some organisms to generate heat

5) A mutation in Adenylate Cyclase would most likely decrease the rate of Gluconeogenesis in liver
