What is required for PKC activation? Choose one: A. binding to Gq and DAG B. binding to Gq C. binding to DAG D. continuing presence of Ca2+ E. binding to DAG and continuing presence of Ca2+ IP3 signaling helps regulate sweating, which is important for regulating body temperature. Anhidrosis, the inability to sweat normally can be caused by genetic and environmental factors. A rare mutation has been identified in a family with several children suffering from anhidrosis. The mutation inactivates the protein that IP3 binds on the ER membrane. Suppose cells were isolated from affected family members and exposed to different treatments. Which of the following treatments would be able to repair the signaling defect in cells isolated from these patients? Choose one: A activation of phospholipase CB in the cell B. addition of high amounts of IP3 in the cell C. addition of high amounts of Ca2+ in the cytosol O D. addition of PKC to the cell
