Cell Signaling and Apoptosis 
Types of Signaling 
• A ligand is a molecule that has specificity for a given receptor, and the binding of a ligand to the given 
receptor causes a change. 
• There is a wide array of cell ligands: hormones, peptides, sugars, and even small, hydrophobic molecules. 
• Regardless of its type, a ligand is always specific for the target receptor. This ligand-to-receptor specificity 
helps to regulate responses in the target cell while not impacting non-target cell...
