WebMar 5, 2024 · Some amino acids can be converted to pyruvate to be used during gluconeogenesis to make glucose. However, fatty acids and ketogenic amino acids cannot be used during gluconeogenesis. WebMar 6, 2024 · 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.
WebThe fatty acids can then be broken down directly to get energy, or can be used to make glucose through a multi-step process called gluconeogenesis. In gluconeogenesis, amino acids can also be used to make glucose. In the fat cell, other types of lipases work to break down fats into fatty acids and glycerol. WebPC is a multisubunit enzyme that has acetyl CoA as a positive allosteric regulator. The enzyme is critical for both gluconeogenesis and fatty acid synthesis, since it provides oxalacetate which {Deceased. is a precursor of malate and citrate, two citric acid cycle. 381. intermediates that leave the mitochondria as part of biosyn- thetic processes.
