How do hormones act on target cells?

Peptide hormones bind to receptors in the cytoplasm and result in the activation of enzymes.

Peptide hormones bind to cell membrane receptors and result in the activation of enzymes. Steroid hormones enter the cell, bind to receptors in the nucleus and activate certain genes.

Steroid hormones enter the cell, usually bind to receptors in the cell membrane and result in the activation of certain genes.

Hormones are raw materials that are naturally converted to end products by the correct target cell.

Hormones are chunks of DNA that are sent out to be incorporated into target cells and become activated to produce hormone products.
