A signal transduction pathway is a series of molecular events that allows a cell to respond to an extracellular signal or stimulus. These pathways are crucial for cellular communication and coordination of various physiological processes. In the context of Comparative Anatomy and Developmental Biology of Vertebrates, understanding signal transduction pathways is essential to comprehend how organisms regulate their development, growth, and responses to environmental cues.

The general steps of a signal transduction pathway in a target cell can be outlined as follows:

1. Reception:
   - The pathway is initiated when a signaling molecule (ligand) binds to a specific receptor protein on the cell membrane or inside the cell.
   - Receptors are often proteins with binding sites ________ ______ ___ _____________ ___________ _________.
