Select all that apply. 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 numbered 2? -Glucose yruvate NADH LDH Lactate --NAD" Liver ich INAD NADH Ble Glucose 2NTP Tyruvate LDH Lactate Muscle low NAD+ INADH ADP → ATP ATP → ADP NAD+ → NADH NADH → NAD+ FAD FADH2 B lecess Important values if needed for this question The reaction n which glucose s phosphoryated to give glucose 6-phosphat e has a AG of 13.8 kl moi. This reaction is coupled with the hydrolysis of ATP, which has a -30.5 kJ mor, what is the ΔG., of the overall reaction? O 16.7 kJ mot 1 C-13.8 KJ mol O 44.3 kJ mot -16.7 ku mor O-44.3 KJ mol

Answer 1

Ans 1 : Fructose-6-phosphate to Fructose-1,6-biphosphate

The build up of ATP in the cells or body inhibit the action of enzyme phosphofructokinase that catalyses the rate limiting step in glycolysis to convert Fructose-6-phosphate to Fructose-1,6-biphosphate. When the body is already rich in ATP , it does not need anymore energy so the breakdown of glucose must be prevented . The ATP binds to the enzyme PFK at its allosteric site and inhibit its action to halt the glycolysis process.
