The primary catabolic pathway in the body is the citric acid cycle because it is here that oxidation to carbon dioxide occurs for breakdown products of the cell’s major building blocks - sugars, fatty acids, and amino acids. The pathway is cyclic (Figure 6.63) and thus, doesn’t really have a starting or ending point.

WebFeb 10, 2012 · The NADH produced in the cytosol by glycolysis cannot enter the mitochondrial matrix, yet it must be oxidized back to NAD + to allow glycolysis to proceed. This can be accomplished by lactate dehydrogenase, as described in Chapter 2.9, but this does not extract the energy of combustion remaining in the lactic acid. Two types of … WebThis reaction is not contained within the citric acid cycle though, and therefore pyruvate kinase does not catalyze any reactions in the citric acid cycle. Each of the other enzymes listed catalyzes reactions within the citric acid cycle, as follows: Isocitrate dehydrogenase catalyzes the conversion of isocitrate to alpha-ketoglutarate. WebMar 6, 2024 · Oxidized carriers, such as NAD+ and FAD are needed by catabolic pathways, like glycolysis, the citric acid cycle, and fatty acid oxidation. Anabolic pathways, such as fatty acid/fat synthesis and gluconeogenesis rely on reduced electron carriers, such as FADH2, NADH, and the related carrier, NADPH. scalawags apush chapter 15
