Identify the reaction(s) of glycolysis inhibited by ATP □ glyceraldehyde-3-phosphate → 1,3-bisphosphoglycerate phosphoenolpyruvate +pyruvate 3-phosphoglycerate ~2-phosphoglycerate 1) fructose-6-phosphate→ fructose-1,6-bisphosphate . glucose glucose-6-phosphate Select all that apply. Alcohol fermentation: consumes ATP as it produces ethanol. O produces carbon dioxide begins as pyruvate is decarboxylated to acetaldehyde in a reaction catalyzed by alcohol dehydrogenase m regenerates NAD requires the enzyme alcohol dehydrogenase, In the figure below, what is the reaction occurring at the location...
The final reaction of glycolysis is catalyzed by pyruvate kinase and has a ΔG’° of -31.4kJ/mol. In vivo this enzyme has a ΔG of -16.7kJ/mol. In gluconeogenic tissues like the liver, the cytosolic concentrations of ATP, ADP, Pi and PEP are 2.25mM, 0.25mM, 1.65mM and 8.8μM respectively. Assuming everything else remains constant, what fold change in pyruvate concentration would be required to drive pyruvate kinase in the reverse direction? (That is, solve the equation when ΔG is 0).
Determine the direction the following reactions will progress. Assume that the reactants and products are present in equimolar amounts.
