Metabolism: The set of chemical reactions that happen in the cells of living organisms to sustain life.

There are 2 types or parts of metabolism

  • Catabolism- the chemical breakdown of organic matter. Seen in cellular respiration.
    • readsorption of old/dead cells
    • digestion
  • Anabolism- the chemical construction of cell components like proteins or nucleic acids.

There are some parts of metabolism that don’t fit in any category.

For example:

  • transport energy, moving products through the organism
