- 1a. If you wanted you could take a glucose molecule and convert it to pyruvate via glycolysis and convert it back to glucose via gluconeogenesis. What is the cost of doing so in ATP equivalents? Show how you determine the cost via reactions (no structures). Explain in bioenergetic terms how the conversion of pyruvate to phosphoenolpyruvate in gluconeogenesis overcomes the large, negative standard free- energy change of the pyruvate kinase reaction in glycolysis. b. C. The consumption of alcohol (ethanol), especially after periods of strenuous activity or after not eating for several hours, results in a deficiency of glucose in the blood, a condition known as hypoglycemia. The first step in the metabolism of ethanol by the liver is oxidation to acetaldehyde, catalyzed by liver alcohol dehydrogenase: CH3CH2OH + NAD+ -> CH3CHO + NADH + H+ Explain how this reaction inhibits the transformation of lactate to pyruvate. Why does this lead to hypoglycemia?arrow_forwarda Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body.

Calculate the weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled.
