The inhibitor of an intracellular signal receptor is defective, such that even when stimulated by a signal molecule, the inhibitor stays bound to the receptor. what effect will this have on the signaling pathway?

When the inhibitor of an intracellular signal receptor is non-functional even when stimulated by a signal molecule, the signal molecule will bind to the receptor, but it will not have the ability to activate it. That is the effect that it will have on the signaling pathway.
