<prompt> Answer this question truthfullyWhat is the role of the αq-GTP complex in the phospholipase C mechanism of cellular signaling, and what are the products of phospholipase C catalysis?  <response>: <reason> The αq-GTP complex activates phospholipase C in the phospholipase C mechanism of cellular signaling. Phospholipase C then catalyzes the liberation of diacylglycerol DAG and inositol triphosphate IP3 from phosphatidylinositol 4,5-bisphosphate PIP2.
