BIO 110 Study Guide - Midterm Guide: Protein Kinase A, Cholera Toxin, Cell Adhesion Molecule
Document Summary
Cell-cell recognition: when adhesion molecules of one cell fit onto the other cell in order to cause a reaction/communication. Local/paracrine/synaptic chemicals: chemicals released for a specific purpose/cell. Long distance/endocrine chemicals: chemicals travel a long distance to reach their target cells (hormones) Reception: the target cell detects the incoming signal. The signal is detected when the chemical signal binds to receptor proteins at the cell surface. Transduction: the conversion of a signal from the outside of a cell to a form that can bring about a specific cellular response. Response: the appropriate behavior or response is carried out by the cell. G protein-coupled receptors- associated with gtp activiates a cellular response by binding and carrying signal. Receptor tyrosine kinases- the enzyme that adds phosphate. Steroid diffuses through cell membrane, then it binds to the receptor and then the steroid alters the gene expression and cell function.
