- 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+. NADH and FADH2, pass their electrons to the electron transport chain, turning back into NAD+ and FAD+ Explain further

Acetyl-CoA Pyruvate FADH2 Glucose-6 phosphateGlycolysis and Krebs cycle produced small amount of energy converted to ATP. Predict the form of the rest usable energy at this point. A. NADH and FADH2 B. Acetyl CoA C. Citrate D. PyruvateWhich of these is associated with production of ATP during glycolysis? (Select all that apply) a) Conversion of 1,3-BPG to 3PG b) Conversion of 1,3-BPG to 2,3-BPG c) Conversion of PEP to pyruvate d) Conversion of 2,3-BPG to 2PG e) Phosphorylation of glucose
- fill in the blanks Complete metabolism of the fatty acid stearate will produce ( ) acetyl CoA, ( ) FADH2, ( ) NADH, and when run through the ETC and ATP synthase, will produce a net of ( ) ATPmyristic acid (14:0) to carbon dioxide and watera. rounds of the beta oxidation pathway will be involvedb. how many moles of acetyl CoA will be produced after complete beta oxidationc. how many moles of ATP will be obtained after complete beta oxidationWhich of these is NOT true of the citric acid cycle? O The citric acid cycle occurs in the mitochondria. The citric acid cycle produces ATP via oxidative phosphorylation. The citric acid cycle produces two ATP per glucose molecule. The citric acid cycle uses both NAD+ and FADH as electron carriers.
