- Before pyruvate enters the citric acid cycle, it is decarboxylated, oxidized, and combined with coenzyme A, forming acetyl CoA, carbon dioxide, and one molecule of (a) NADH (b) FADH2 (c) ATP (d) ADP (e) C6H12O6Calculate the amount of ATPthat can be produced fromone molecule of 8:0 fatty acid metabolized aerobicallythrough ß-oxidation cycle and the citric acid cycle.a) Metabolic process in which hexose metabolism occurs? Amount of steps? Since this metabolic process (hexose -> 2 pyruvate) is exergonic. b) But, looking at the individual reactions that makeup this process, they are a combination of exergonic and endergonic reactions. (true or false). If false, explain why. If true explain the contribution of endergonic reactions to the overall exergonic process.
- 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.Thioester play an important role in glycolysis and the TCA cycle. Which reactions in glycolysis and tca cycle involve thioesters.Each acetyl CoA that enters in the citric acid cycle, 2 carbon dioxide molecules are released in reactions which are coupled with the production of NADH molecules from reduction of NAD+ molecules and FADH2 is alse released by reduction of FAD+.
