Here's the breakdown:

1. PIP2 is a phospholipid located in the cell membrane.

2. PLC is activated by various signaling molecules like hormones, neurotransmitters, and growth factors.

3. Activated PLC cleaves PIP2 into two products:

* Diacylglycerol (DAG): This remains embedded in the cell membrane.

* Inositol trisphosphate (IP3): This diffuses into the cytoplasm.

So, DAG is a direct product of PIP2 hydrolysis by PLC.
