Catabolism is the breaking down of molecules into smaller units (proteins to amino acids) resulting in the release of energy.
Anabolism is the construction of larger molecules from smaller units (amino acids to proteins) which requires energy.
Metabolism is set of chemical reactions that occur in living organisms to maintain life. Anabolism and catabolism are two categories of metabolism and since the question includes both anabolism and catabolism this should be the answer.
Homeostasis is the property of a system that regulates its internal environment to maintain it at a stable, constant condition.
Differentiation (in a biological/cellular context) is the process by which a less specialized cell becomes a more specialized cell type.
