- Signal transduction: Process by which cells detect and respond to external signals
- Types of cellular signaling: Endocrine, paracrine, autocrine, and contact-dependent signaling
- Components of pathways: Ligands, receptors, second messengers, protein kinases, and phosphatases
- G Protein-Coupled Receptor (GPCR) Pathway: Involves activation of G protein and production of second messengers
- Receptor Tyrosine Kinase (RTK) Pathway: Activation leads to diverse cellular responses, such as cell growth and differentiation
