A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
Similarly, it is asked, how do most hormones get to their target?
Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell's activities.
Where are hormone receptors located on cells of the body?
Consequently, receptors for peptide hormones are located on the plasma membrane because they have bound to a receptor protein located on the plasma membrane. Water-soluble hormones come from amino acids and are located and stored in endocrine cells until actually needed.
How does the onset of puberty related to the endocrine system?
How is the onset of puberty related to the endocrine system? Puberty starts when the hypothalamus signals the pituitary gland to begin producing two hormones, which in turn signal the reproductive glands to produce sex hormones.
