Which molecule is commonly involved as a second messenger in cell signaling?
Step 1: Understand what a second messenger is. A second messenger is a molecule that helps transmit signals inside a cell after a receptor on the cell's surface is activated.
Step 2: Identify a common second messenger. One well-known second messenger is cyclic AMP, often abbreviated as cAMP.
Step 3: Learn how cAMP works. When a signal (like a hormone) binds to a receptor on the cell, it can lead to the production of cAMP inside the cell.
Step 4: Recognize the role of cAMP. cAMP then carries the signal to other molecules inside the cell, helping to trigger a response or action.
