Lesson 2: Introduction to Signal Transduction
Duration of Days: 2
Lesson Objective
Describe the components of a signal transduction pathway and explain how the binding of a ligand to a receptor initiates a cellular response.
How is a chemical signal outside a cell converted into a specific functional response inside the cell?
What determines whether a signaling molecule (ligand) binds to an intracellular receptor versus a membrane-bound receptor?
4.2- Introduction to Signal Transduction
There is a molecular bridge between a cell's exterior environment and its interior operations. It allows for a generic chemical signal outside a cell to cause a highly specific structural change inside the cell.
