Step by step
Solved in 3 steps
- How many more acetyl CoA are generated from stearic acid than from linoleic acid during beta oxidation?When one of the acetyl CoA is processed through the citric acid cycle, how many times does a secondary alcohol group is oxidized to a ketone group?Acetly CoA can quickly enter the citric acid cyle by joining with a C4 compound and forming citrate. Meanwhile, GTP (or ATP) is generated using inorganic phosphate while succinyl CoA is converted to succinate. What is the main reason both acetly CoA and succinyl CoA can perform such work? a. Acetyl CoA and succinyl CoA both contain coenzyme A, which is a high-energy compound. b. Acetyl CoA and succinyl CoA both form an unstable thioester bond with coenzyme A. c. Acetyl CoA and succinyl CoA both bind with inorganic phosphate which is used to generate ATP (or GTP). d. Acetyl CoA and succinyl CoA both transiently form a covalent bond with the enzymes that catalyze the next reaction, pyruvate dehydrogenase and succinyl-CoA synthetase, respectively. e. Acetyl CoA and succinyl CoA use the energy collected from the electron transport chain.
- On these following choices, Malonyl CoA synthase, Malonyl CoA synthetase, Acetyl CoA carboxylase and Acetyl CoA decarboxylase, what is the correct answer in fatty acid synthesis?If the carbonyl carbon of acetyl-CoA were marked with 14C, where would that carbon be located within oxaloacetate after one turn of the TCA cycle?How many moles of Acetyl CoA are produced from the beta oxidation of Lauric Acid?
- Which of the following statements is/are TRUE for the Krebs' cycle? Reaction 1: condensation of acetyl-CoA and oxaloacetate; produces H20. Reaction 3: oxidation of isocitrate to a-ketoglutarate; produces NADH and CO2. Reaction 6: oxidation of succinate to fumarate; produces FADH2 and CO2 Reaction 5: hydrolysis of succinyl-CoA to succinate; produces ATP.What is the final fate of the carbons in acetyl-CoA after several turns of the citric acid cycle?Why is the citric acid cycle the most efficient way to oxidise Acetyl CoA?
- How many molecules of acetyl CoA, FADH2, and NADH are produced in the catabolism of a molecule of arachidonic acid, an 20-carbon carboxylic acid? How many times does the spiral reaction sequence occurTwo carbon atoms are fed into the citric acid cycle as acetyl-CoA. In what form are two carbon atoms removed from the cycle?Why is acetyl-CoA considered the central molecule of metabolism?
