Regulatory mechanisms are processes that help maintain balance and control within biological systems. They ensure that various functions, such as metabolism and growth, occur at appropriate levels. These mechanisms can involve hormones, enzymes, and feedback loops that respond to changes in the environment or internal conditions. In addition to biological systems, regulatory mechanisms are also important in fields like environmental policy and financial markets. They involve rules and guidelines that govern behavior, ensuring compliance and promoting stability. By establishing standards, these mechanisms help prevent crises and protect public interests.
