Document Summary
Exam 3: drugs, drug metabolism, and whether drug metabolism differs between typically identified races. Drugs are chemicals that mimic normal body chemicals and have effects on body functions. Drugs are usually small molecules that interact w/ proteins. They can act on membrane receptors, enzymes, and intracellular proteins. Each drug interacts with a class of protein. Drugs can be more or less specific in action. Effects of a drug depend on what body tissues express the protein the drug interacts with; one drug can have multiple effects if it acts on similar proteins. An agonist is any drug that activates protein (ex. An antagonist is any drug that blocks the protein (ex. Curare-blocks ach receptors and blocks muscle contraction, used during surgery). Drugs metabolism is getting rid of drugs before they do too much harm. A drug is seen by the body as a toxin.
