Which of the following mechanisms can terminate an intracellular signaling pathway once the concentration of an external signal decreases?

Question

Quizplus · Accepted Answer

All of the listed mechanisms can terminate or dampen an intracellular signaling pathway once the concentration of an external signal decreases. Degradation of the second messenger eliminates the intracellular messenger molecules, while desensitization of receptors decreases their activation by ligands. Deactivation of signal transduction proteins or enzymes reduces the enzymatic activity or function of the downstream effectors. These processes contribute to maintaining the dynamic balance and responsiveness of signaling networks.
