1. Glycolysis: The breakdown of glucose into pyruvate, which can then be further catabolized to produce energy.
2. Proteolysis: The breakdown of proteins into amino acids, which can then be used to build new proteins or catabolized to produce energy.
3. Lipolysis: The breakdown of lipids into fatty acids and glycerol, which can then be catabolized to produce energy.
Anabolic processes
1. Gluconeogenesis: The synthesis of glucose from non-carbohydrate sources, such as amino acids or fatty acids.
2. Protein synthesis: The synthesis of proteins from amino acids.
3. Lipogenesis: The synthesis of lipids from fatty acids and glycerol.
