For each of the following sentences, select the best word or phrase from the list below to fill in the blanks.Not all words or phrases will be used; each word or phrase should be used only once.
$\begin{array}{lll}\text { acetylase } & \text { decouple } & \text { GTP-binding } \\\text { AMP-binding } & \text { decrease } & \text { neurotransmitter } \\\text { amplify } & \text { effector } & \text { protein kinases } \\\text { autocrine } & \text { esterases } & \text { protein phosphatases } \\\text { cleavage } & \text { integrate } & \text { receptors } \\\text { convolute } & \text { GMP-binding } & \text { sterols }\end{array}$

An extracellular signal molecule can act to change a cell's behavior by acting through cell-surface that control intracellular signaling proteins.These intracellular signaling proteins ultimately change the activity of proteins that bring about cell responses.Intracellular signaling proteins can the signal received to evoke a strong response from just a few extracellular signal molecules.A cell that receives more than one extracellular signal at the same time can this information using intracellular signaling proteins. proteins can act as molecular switches, letting a cell know that a signal has been received.Enzymes that phosphorylate proteins, termed , can also serve as molecular switches; the actions of these enzymes are countered by the activity of __.
