What happen when a hormone bind to a receptor?

When a hormone binds to a receptor, it triggers a conformational change in the receptor, activating it. This activation initiates a signaling cascade within the cell, leading to various biological responses, such as changes in gene expression, metabolism, or cellular activity. The specific outcome depends on the type of hormone and receptor involved, as well as the target cell's characteristics. Ultimately, this process enables the hormone to exert its effects on physiological functions and homeostasis.
