BIOL 2051 Chapter : Chapter 2 Notes
Document Summary
Chapter overview: morphology of bacterial cells, the cytoplasm, the bacterial cytoskeleton, the cell envelope, the bacterial cell surface, bacterial taxonomy. Morphology of bacterial cells: common bacterial shapes/morphologies, spherical (s. coccus, pl. cocci, rod-shaped (s. bacillus, pl. bacilli, spiral (s. spirillum, pl. spirilla) Chapter 2: bacteria: comma-shaped (s. vibrio, pl. vibrios, pleiomorphic (varied shapes, size of bacteria can vary greatly, usually smaller than eukaryal cells (bacteria are often. The bacterial cytoskeleton: what kinds of internal structures help to organize bacterial cells, cytoskeloton- proteins that assist in keeping everything in (or moving it to) the correct locations in cells. Against a concentration gradient: co-transport mechanisms (symport/antiport, symport both substances go into the cells, antiport both substances go in opposite direction, atp-binding cassette (abc) transporters, requires energy. Chapter 2: bacteria: n-acetylglucosamine (nag, several of the amino acids found associated with nam in peptidoglycan are unusual d forms, d forms are stereoisomers (mirror images) of the l forms normally found in biological proteins.
