A target cell is a cell that has receptors for a specific hormone or other signal molecule. In the context of cell signaling, the "target" is typically a specific protein within the cell that the signal molecule will bind to, initiating a specific cellular response. Here are the steps that describe how a target cell responds to a signal molecule:

1. Signal molecule (also known as a ligand) approaches the target cell.

2. The signal molecule binds to a specific receptor on the surface of the target cell. This receptor is specific to the signal molecule, much like a lock and key.

3. This binding event triggers a change in the shape of the receptor, which initiates a series of events inside the cell, often involving other proteins.

4. These events lead to a specific response within the cell, such as changing the cell's metabolism, initiating cell division, or producing a specific protein.

5. Once the response has been carried out, the signal molecule is released from the receptor and the receptor returns to its original shape, ready to receive another signal molecule.
