Quizplus · Accepted Answer

Inositol triphosphate (IP3) is rapidly inactivated enzymatically by phosphatases in the cytoplasm and endoplasmic reticulum, which converts it into inositol diphosphate (IP2) or inositol monophosphate (IP1). This enzymatic dephosphorylation makes the effect of IP3 transient and short-lived.
