Below are statements regarding the body's inability to convert fat to carbohydrates. Select the statements that are true. There is more than one correct answer. Select all the correct answers. The acetyl CoA that is produced from the oxidation of fatty acids enters the citric acid cycle, but does not lead to a net gain of pyruvate. Metabolism of odd-chain fatty acids yields propionyl CoA, which is converted to succinyl CoA and can enter the citric acid cycle. The decarboxylation...
