Answer:
D. Each receptor triggers one particular type of cell behavior, for example, activating gene expression.
Explanation:
- Each extracellular signal molecule can induce different responses depending on the target cell.
- Lipophilic receptors diffuse or carried across the cell's plasma membrane and bind to an intracellular receptor. For example steroid hormones are transported via carrier proteins.
- Some signalling molecules only induce response from specific cells.
- A single receptor can be activated by different signal molecules.
