Glycolysis and gluconeogenesis are concurrent and complementary metabolic pathways. Which of the following IS NOT TRUE a) glycolysis and gluconeogenesis regulate the availability of glucose in the cell b) all enzymes and intermediates used in glycolysis and gluconeogenesis are the same, glucose, respectively anabolizes acetyl-CoA and pyruvate to glucose. fructose 16P into fructose 6P (final step) in gluconeogenesis uses pathway specific ) glycolysis catabolizes glucose to pyruvate and acetyl-CoA and gluconeogenesis d) the conversion of pyruvate into phosphoenolpyruvate (first step)...
What is the fate of the acetyl CoA produced during beta oxidation? O It is sent to the electron transport chain for further processing. It is deaminated. o It enters glycolysis It enters the Kreb's cycle.
8. Draw the overall coupled reaction showing the conversion of pyruvate into acetyl CoA. dono STEP 2 nach do not ww what are true. Ir raise, change one word in the statement so that it is true. a. The pyruvate produced from glycolysis must be consumed in some way or glycolysis stops. b. Glycolysis produces ATP directly. too C. Glycolysis breaks down glucose into acetyl CoA. d. Glycolysis is aerobic
5. As indicated in the KEGG pathways for fatty acid degradation and biosynthesis which pathway does NOT use acetyl-CoA as a substrate? A. citric acid cycle B. butanoate metabolism C. fatty acid biosynthesis D. glycolysis 6. Which statement is consistent with the comparison of fatty acid biosynthesis in humans and in Helicobacter pylori 2017? A. Both organisms use the same multifunctional enzyme B. Humans use separate proteins to catalyze each step, while H. pylori 2017 uses one multifunctional enzyme to...
What is the chemical reaction that involves oxaloacetate and acetyl-coa in the tca cycle? a. hydration b. oxidation c. reduction d. hydrolysis e. none of the above
Which of the following produces the most ATP when glucose is completely oxidized A. Fermentation B. All of these processes produce about the same amount of ATP C. Oxidation of pyruvate to acetyl-CoA D. Citric acid cycle E. Glycolysis F. Oxidative phosphorylation
Match the following nutrients with the stage at which they can
directly enter the ATP-production pathway
Stage 2: Ketogenic amino acids, glucose, and fatty acids are converted to acetyl COA Acetyl COA Stage 3: Acetyl CoA enters the TCA cycle, releasing GTP, hydrogen ions and their electrons, and Co, Some amino acids can be converted to intermediate TCA compounds. TCA Cycle Stage 4: The coenzymes NADH+H and FADH, release the hydrogen ions and their electrons in the electron transport chain,...
From the information in Chapter 8 on metabolism and Appendix A, we can see the multiple metabolic pathways involved in generating ATP from the breakdown of the nutrients glucose, protein and fats. Glycolysis generates pyruvate, the pyruvate then becomes Acetyl CoA, which enters the Krebs Cycle (TCA), products of the Krebs Cycle then enter the Electron Transport Chain (ETC) where ATP is the final product. Fat breakdown (beta-oxidation) also generates Acetyl CoA, which then enters the Krebs Cycle to produce...
Which of the following statements regarding catabolic pathways are true? 1. When proteins are used as a source of energy for the body, the proteins are first broken down to produce amino acids, which are then converted into either glyceraldehyde 3 phosphate or acety CoA The enzyme phosphofructokinase is subject to allostericinhibition by high levels of citric acid When acety CoA builds up in the call it increases the activity of the enzyme that synthesizes oxalacetato from pyruvate and carbon...

Oxidative phosphorylation Substrate level phosphorylation Oxidation of NADH Photosynthesis Fermentation 1 points QUESTION 2 Phosphofructokinase (PFK-1) is one of the most regulated enzymes in metabolism. Which of the following would be expected to be an allosteric inhibitor of PFK-1?
