Answer:
The mechanism by which cells regulate their ability to respond to extracellular messengers is known as receptor signalling.
Explanation:

Endocytosis regulates cell signalling by controlling the number of receptors available for activation in plasma membrane and activation of receptors or downstream effectors often stimulate receptor endocytosis.
