Metabolism can be conveniently divided into two categories:

  • Catabolism – the breakdown of molecules to obtain energy.
  • Anabolism – the synthesis of all compounds needed by the cells.

Metabolic reactions may be categorized as catabolic – the breaking down of compounds (for example, the breaking down of glucose to pyruvate by cellular respiration); or anabolic – the building up (synthesis) of compounds (such as proteins, carbohydrates, lipids, and nucleic acids).

What happens to metabolism during fasting?

In fact, short-term fasts may increase your metabolic rate.
