Modes of nutrition

  • David Harrison


All living organisms require a source of energy with which to perform vital functions such as active transport, the movement of cell organelles leading to locomotion or cell division, and biochemical syntheses (see Part I). At a cellular level this energy is provided in the terminal phosphate bond of ATP. Nutrition consists of the supply of substrates to the biochemical pathways by which ATP is produced. Nutrition also provides substrates for the biochemical pathways which lead to the formation of tissues in growth.
