Question

Typically, receptors for hormones or growth factors are destroyed during endocytosis, leading to a reduction in the cell's sensitivity to further stimulation by that particular hormone or growth factor. This is a mechanism by which cells regulate their ability to respond to extracellular messengers. What is it called?

Answer 1

Answer:

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

Explanation:

Cells senses an environment and communicate which each other through ligand-induced activation of signalling receptors at the cell surface. Signalling receptors enter the endocytic pathway and are sorts into various compartments. 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.
