Give examples of how signal transduction results in cellular responses.
Added by David W.
Step 1
**G-protein coupled receptors (GPCRs):** When a ligand binds to a GPCR, it activates a G-protein, which then activates an effector enzyme, such as adenylyl cyclase. This enzyme converts ATP to cyclic AMP (cAMP), which acts as a second messenger, leading to a Show more…
