Verified step by step guidance

Understand that hormones are chemical messengers that travel through the bloodstream to target cells.

Recognize that for a cell to respond to a hormone, it must have specific receptors on its surface or inside the cell that can bind to the hormone.

Learn that these receptors are proteins that have a unique shape, allowing them to bind only to specific hormones, much like a lock and key mechanism.

Consider that the presence of these receptors is crucial; without them, the hormone cannot exert its effect on the cell, regardless of other factors like blood supply or proximity to the gland.

Note that while blood supply and proximity to the gland can influence the delivery of hormones, they do not determine the cell's ability to respond. The key factor is the presence of specific receptors for the hormone.
