True or False: All lipophilic hormones bind with intracellular receptors and primarily produce effects in their target cells by activating specific genes that cause the synthesis of new proteins. True. WebA 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.
