In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.

Answer: Dont quote me on this but im pretty sure its south and north
Explanation: because of the north and south poles have the strongest gravatational pulls it combines with the moon rotating and causes stronger tides
