Question

Quizplus · Accepted Answer

Desensitization involves reducing the response of a cell to a ligand, which can occur through receptor down-regulation, receptor-mediated endocytosis, or lowering the affinity of a receptor for the ligand. Destruction of the ligand, however, would simply remove it from the system and would not affect the cell's sensitivity to it.
