All of the chemical reactions that occur in a cell are called
Marie Curie. The reactions that occur in cells are both anabolic (building up) and catabolic (breaking down). The catabolic reactions provide the energy for the anabolic reactions. The sum total of all catabolic and anabolic reactions in the cell is called metabolism.ome examples of chemical reactions that occur in the cell are cellular respiration, protein synthesis, DNA replication, and transcription. 3 people found this useful.
