Pharmacology and Cell Signaling Quiz

Introduction to Pharmacology and Cell Signaling

• Pharmacology is the study of the interaction between a chemical substance and a living system.
• A drug is a chemical substance, natural or synthetic, that can affect a biological or living system.
• Pharmacology has two main subdivisions: pharmacodynamics and pharmacokinetics.
• Pharmacodynamics describes the effect of a drug on the body, its mechanism of action, and its binding to a receptor.
• Pharmacokinetics describes the effect of the body on the drug, including absorption, distribution, metabolism, and elimination.
• Cell signaling is how cells communicate with each other using chemical compounds called ligands.
• Ligands are proteins or other molecules produced by a sending cell and released into the extracellular space.
• Receptors are macromolecule structures made of protein chains that receive and interact with ligands to produce a physiological or pharmacological effect.
• Signal transduction is the series of biochemical and molecular activity changes occurring inside the cell following ligand-receptor binding.
• Receptors are classified into two main categories: cell surface or transmembrane receptors and intracellular receptors.
• Cell surface transmembrane receptors include ligand-gated ion channel receptors, G-protein coupled receptors (GPCRs), and enzyme-coupled receptors.
• Understanding pharmacology and cell signaling is important for developing drugs that can effectively target specific receptors and produce desired physiological or pharmacological effects.
