Nutrition and Metabolism (Ch. 26)
Differentiate between anabolism and catabolism
• Anabolism is an endergonic reaction: energy is consumed as the reaction takes place
o Build up
o Anabolic reactions create bonds between small molecules to make large
molecules (polymers)
o Example: protein synthesis
• Catabolism is considered an exergonic reaction; energy is released as the reaction takes
place
o Break down
o Catabolic reactions break bonds in large molecules (polymers), to make small
molecules
o Example: digestion of starch to glucose
• Anabolism + catabolism = METABOLISM
Define the terms gluconeogenesis, glycogenesis, glycolysis, and glycogenolysis
• Gluconeogenesis:
o Formation of new glucose, from non-carbohydrate sources (lactic acid,
glycerol, or an amino acid)
▪ Anabolic reaction
▪ “gluco” = “glucose”
▪ “neo” – new
▪ “genesis” = creation
• Glycogenesis:
o Excess glucose taken up the liver and converted into glycogen
▪ Anabolic reaction
▪ Stimulated by insulin
▪ “glycogen” = glycogen
