Verified step by step guidance

Understand the phosphoinositide signal transduction system, which is a pathway that involves the conversion of a signal from outside the cell into a functional response inside the cell.

Identify the role of effector enzymes in signal transduction pathways. Effector enzymes are responsible for generating second messengers that propagate the signal within the cell.

Recognize that in the phosphoinositide pathway, the effector enzyme is responsible for hydrolyzing phosphatidylinositol 4,5-bisphosphate (PIP2) into two second messengers: inositol trisphosphate (IP3) and diacylglycerol (DAG).

Recall that Phospholipase C (PLC) is the enzyme that catalyzes the hydrolysis of PIP2 into IP3 and DAG, making it the effector enzyme in this pathway.

Differentiate between the roles of other enzymes mentioned: Adenylate cyclase is involved in the cAMP pathway, and Protein Kinase C is activated by DAG but is not the effector enzyme in the phosphoinositide pathway.
