💡Explanation :-
- Activation of Gq coupled receptors leads to the activation of phospholipase C (PLC) , which in turn catalyzes the hydrolysis of phosphatidylinositol 4,5 bisphosphate (PIP2) into inositol trisphosphate (IP3) and diacylglycerol (DAG) .
- IP3 then binds to its receptor on the endoplasmic reticulum, causing the release of calcium ions (Ca2+) into the cytoplasm, while DAG activates protein kinase C (PKC).
- These second messengers, IP3 and DAG, play crucial roles in various signaling pathways, including intracellular calcium release and PKC-mediated signaling.
