Practice: Carbohydrate metabolism questions. Carbohydrate catabolism. Explanation: Krebs cycle The Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is one of the most important reaction sequences in biochemistry. The Krebs cycle produces two molecules of ATP for every molecule of glucose. The Krebs cycle also produces eight molecules of NADH and two molecules of FADH2 per molecule of glucose. NADH and FADH2 are later used to produce energy during electron transport phosphorylation. During the process of aerobic respiration, one molecule of glucose is first broken down into two molecules of pyruvate. During digestion, carbohydrates are broken down into simple, soluble sugars that can be transported across the intestinal wall into the circulatory system to be transported throughout An important example of an amphibolic pathway is the Krebs cycle, which involves both the catabolism of carbohydrates and fatty acids and the synthesis of anabolic precursors for amino-acid synthesis (e.g. What are the reactants in the Krebs cycle quizlet?Photosynthesis.
