Explanation:

In living organisms, control processes similar to the control processes used in technology take place in a purely formal way, one can look at living beings as cyber machines. Governance and regulation are fundamental principles of the organization of the living. According to the type of signal or transmission of information, four different types of biological control processes are distinguished:

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