Hello Student
Correct answer is 3. Ionositol triphosphate (IP3)
Ionositol triphosphate (IP3) is formed by the degradation of phosphatidy ionositol 4,5-biphosphate (P1P2) by the enzyme phosphodiesterase. IP3 acts as interacellular secondary messanger and helps to amplify the hormonal signal by stimulating the release of Ca++from ER target cells.
