Document Summary
Compared to eukarya, have similar mechanisms of transcription (rna synthesis) and translation (protein synthesis). Unique to archaea, have unique rrna structure, unique lipids, unique metabolisms. Much like bacteria, cocci and rods are common. Bacterial plasma membrane = bilayer with ester-linked phospholipids. Archaea do not have peptidoglycan in their cell walls. All the usual components (nucleoid region, inclusion bodies, ribosomes) iclicker question: To move to an area of high concentration, energy-costly active transport is needed. Protists, algae, fungi, human pathogens (why hard to kill, think targeting synthesis of peptidoglycan). Target pathogenic cell membranes, risk targeting the patient"s membranes as well. Structurally, more complex and generally larger than bacterial or archaeal cells. Plasma membrane is a lipid bilayer containing fatty acids and ester linkages (similar to bacteria). Intricate complex of membranous organelles and vesicles that move materials into the cell from outside, outside from inside, and within the cell itself. Function: transport of proteins, lipids and other materials within cell.
