Biological membranes are asymmetrical two leaflets have distinct lipid composition differe(cid:374)t i(cid:374) ter(cid:373)s of what"s a(cid:374)(cid:272)hored to it: outer leaflet often contains glycolipids and glycoproteins (glycol = carbohydrate attached) Features held in both prokaryotic and eukaryotic cells: plasma membrane of similar construction, genetic information encoded in dna using identical genetic code similar mechanisms for transcription and translation of genetic info, including similar ribosomes. 3 types of gated channels: voltage-gated channels: channel responds to changes in ionic charge across membranes, mechano-gated channels: channel responds to physical force on membrane (stretch or. Ligand-gated channels: channel responds to binding of specific molecule (a ligand) relaxation of a stretch) Endo-membrane system: system of sheets connected by tubes 3d: membranous vesicles, extensive network of (cid:373)e(cid:373)(cid:271)ra(cid:374)ous (cid:272)a(cid:374)als a(cid:374)d sta(cid:272)ks of (cid:862)sa(cid:272)s(cid:863) cisternae, endoplasmic reticulum (er, golgi complex lysosomes / vacuoles, vesicles.
