According to the type of signal or transmission of information, four different types of biological control processes are distinguished:

  1. Neural
  2. Hormonal
  3. Differential gene expression in which substrate or substrate-like effectors are signaling agents.
  4. Feedback and forward control mechanisms in which the metabolites themselves act as direct signals to control their own degradation or their own synthesis.
