Guided Notes
Key concepts students will learn:
- •
Autocrine signals affect the same cell that produces them, while paracrine signals affect nearby cells, and endocrine signals affect distant cells.
- •
Hydrophobic ligands can diffuse across the cell membrane and bind to receptors inside the cell, whereas hydrophilic ligands bind to transmembrane receptors on the cell surface.
- •
The three main classes of transmembrane receptors are G protein-coupled receptors, enzyme-coupled receptors, and ion channel receptors.
