Which NUMBER(S) indicate NADH production in the overall process? *
the first two reactions in glycolysis associated with unfavorable ∆G° values, i.e., ∆G° > 0, both produce a product with high phosphoryl group transfer potential. (ATP formation is not considered here.) Compare the two reactions and describe what the driving force is for both reactions that allows glycolysis to proceed to formation of pyruvate.
Under anaerobic conditions, pyruvate will be converted to lactic acid. Why does this occur? To convert NADH to NAD* to feed back into glycolysis To supply the glycolysis reaction glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with needed electrons in the form of NADH Because lactic acid can be converted to glucose to feed back into glycolysis Because lactic acid is needed to resupply glycolysis with electrons O
What is the process that sustains the redox balance of glycolysis under aerobic conditions? transport of lactate from the cell regeneration of NAD* in the citric acid cycle formation of NADH in the reaction of glyceraldehyde 3-phosphate dehydrogenase regeneration of NAD* in fermentation processes regeneration of NAD* in the mitochondrial electron-transport chain
Imagine a triglyceride comprised of (3) saturated C12 fatty acids. Calculate the number of ATP generated from the complete oxidation of one of these 12-carbon fatty acids to CO2 and water in the liver. Assume that each NADH = 2.5 ATP and each FADH2 = ETC generates 1.5 ATP. Any step that yields pyrophosphate as a product should be treated as an input (i.e. net loss) of (2) ATP.
Determine the ATP production of glucose catabolism by glycolysis and Krebs Cycle using the following information: 1. Glycolysis: Net 2 ATP, 2 NADH + H+2. Pyruvate --> acetyl CoA: Produces 2 NADH + H+/glucose3. Krebs Cycle --> 2 FADH2 + 2 ATP + 6 NADH + H+/glucose 2.5 ATP are produced/NADH + H+ delivered electron to the electron transport system1.5 ATP are produced/FADH2 delivered electron to the electron transport system
ATP is an ALLOSTERIC INHIBITOR of the phosphofructokinase enzyme, which is a key catalyst for one of the first steps of Glycolysis. Citrate (citric acid) is a 6-carbon product of the first reaction of the Krebs Cycle (aka Citric Acid Cycle). Interestingly, Citrate enhances the inhibitory effect of ATP on phosphofructokinase. What is a likely explanation for the inhibitory effects of these molecules? Excess ATP and Citrate signal the cell that Glycolysis should be speeded up. Excess ATP and Citrate signal a positive feedback loop. Excess ATP and Citrate signal the cell that Glycolysis should be slowed. Excess ATP and Citrate compete for the active site of phosphofructokinase.
upon digestion of starch maltose, one of its degradation products is further hydrolyzed into its monosaccharide components prior to intestinal absorption and entry into the glycolysis. calculate the number of ATP molecules produced from the digestion and complete oxidation of 1 molecule of maltose considering the glycerol-3-phosphate shuttle. question: 4. what is the total number of CO2 released right after the pyruvate dehydrogenase complex reaction
During glycolysis, the major energy generating step involves: pyruvate kinase phosphoglycerate kinase Phosphofructokinase glyceraldehyde-3 -dehydrogenase
threose-4 phosphate (a 4 carbon aldose) is fed into glycolysis after a decarboxylation reaction that uses an NAD+ to generate a 3 carbon aldose. How many ATP and NADH are generated by breaking down this molecule to pyruvate?
Explain Why Synthesizing Glucose from Pyruvate in the Anabolic Process of Gluconeogenesis requires more energy than is captured during the Catabolic Process of Oxidizing Glucose (through glycolysis) to Pyruvate - How much of the energy (what percentage) of oxidizing Glucose to Pyruvate is captured in Catabolism as NADH (+ H+) and ATP ? - What happens to the rest of the energy of oxidizing Glucose to Pyruvate? How much energy (what percentage) is needed to synthesize Glucose from Pyruvate?
