Target cells are equipped with specific receptor molecules and may occur in any part of the body. ACTH has target cells that are in the adrenal cortex.

What determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
Which substances are found on cell surfaces and respond to nerve and hormone signals?
Receptor molecules are found on cell surfaces and respond to nerve and hormone signals.
Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
Hormone and receptor interactions are based on?
The target cell, the receptor, and the species.
Why hormones can contact virtually all the cells of your body yet only activate the appropiate target cells?
The receptor molecules have the " lock " that the " key " of the hormone fits into . Surface markers, generally glycoproteins, must match up for the hormone to dock at the cell and a signal transduction pathway is then initiated.
How do hormone and target cell recognize one another?
Hormones are specific molecules released by endocrine glands into the bloodstream. Each hormone binds to a specific receptor protein on the surface of the target cell. The receptor protein acts like a lock and key, ensuring that only the specific hormone can bind and trigger a cellular response in the target cell.

Receptor molecules are found on cell surfaces and respond to nerve and hormone signals.
Do viruses require specific receptors to infect cells?
Yes, all viruses need to bind to specific receptor molecules on the surface of target cells to initiate infection. Virus-receptor binding is highly specific, and this specificity determines both the species and the cell type that can be infected by a given virus.In some well-studied cases, the virus-binding region on the receptor has been found to be unrelated to the receptor's normal cellular function.

The target substance of a drug is called?
A receptor.
What is found in or on a hormone's target cell?
Hormone receptor
Which hormone affect only certain cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
