Cultured cells are treated with an experimental agent that leads to rapid increases in cytoplasmic calcium concentrations and an increase in cellular diacylglycerol concentrations. This experimental agent most likely stimulates which of the following?

A) Adenylyl cyclase
B) GTPase-activating protein
C) Phospholipase C
D) Protein kinase A
E) Protein kinase C

Because the questions stem asks you 2 tell what causes an increase in i/c calcium and DAG levels... Phospholipase c does that. Protein kinase C activity is afterwards stimulated by the increased DAG and calcium levels caused by IP3...
