Mechanisms of hormone action. Hormones bind to receptors on the plasma membrane. The hormone itself is the first messenger. Binding to the receptors activates a second messenger inside the cell. The second messenger causes intracellular effects

Hormones work. Vector. When a hormone outside of a capillary, it can act on a target cell. A steroid hormone is capable of crossing through the cell membrane of the target cell. A protein hormone attaches to the cells membrane and activates a receptor that releases, in turn, a messenger within the cell.
