Which of the following is an example of a second messenger in a cellular signaling pathway? a. ATP b. Adenylyl cyclase c. G protein d. Phospholipase c e. Diacylglycerol
Understand the Problem
The question is asking for an example of a second messenger involved in cellular signaling pathways. It presents multiple choices, and we need to identify which one qualifies as a second messenger.
Answer
Diacylglycerol
The final answer is Diacylglycerol.
Answer for screen readers
The final answer is Diacylglycerol.
More Information
Diacylglycerol (DAG) functions as a second messenger in cellular signaling pathways. It is formed when phosphatidylinositol bisphosphate (PIP2) is cleaved by the enzyme phospholipase C. This signaling pathway is crucial in responding to extracellular signals.
