Verified step by step guidance

Understand the role of Phospholipase C: Phospholipase C is an enzyme that plays a crucial role in cell signaling by hydrolyzing phosphatidylinositol bisphosphate (PIP2) into two important secondary messengers.

Identify the substrates and products: Phospholipase C uses phosphatidylinositol bisphosphate (PIP2) and water as substrates. The enzyme catalyzes the reaction to produce inositol triphosphate (IP3) and diacylglycerol (DAG) as products.

Clarify the exception: The problem states that diacylglycerol phosphate is listed as a product, which is incorrect. Phospholipase C does not produce diacylglycerol phosphate; it produces diacylglycerol (DAG) instead.

Review the chemical reaction: The reaction can be represented as:

{PIP}_{2} + H 2 O \to {IP}_{3} + DAG

. This equation shows the substrates and products involved in the reaction catalyzed by Phospholipase C.

Conclude with the correct answer: Based on the understanding of the reaction, diacylglycerol phosphate is not a product of the reaction catalyzed by Phospholipase C, making it the correct answer to the problem.
