BIOL 1110 Lecture Notes - Lecture 26: Bacilli, Defence Mechanisms, Peptidoglycan
Document Summary
Nutrient - any needed by an organisms to survive, grow and reproduce n,s,c etc. Pp- pc-ps-tc-cc: bacteria will function was symbionts. Symbiosis: it"s the living together two or more species in a prolonged and close relationship. Coevolution: reciprocal evolutionary interaction and driven by natural selection. Cattle give bacteria shelter and benefit from the breakdown of cellulose. Carbohydrate release via bacterial cellulose: domain bacteria characteristics, structurally simple. Small size in comparison to a eukaryotic cell. Dna congregate in a nucleotide. (no membrane) Rna, enzymes and ribosomes are going to occur in proximity to nucleotide. Bacteria: peptidoglycan. (modified protein with an attached carbohydrates) You kill gut fauna- don"t poop so well. Helps in mobility: domain archaea, resemble bacteria in a # of ways, small size in comparison to eukaryotes, lack membrane bound organelles and a nucleus, cells wall in most but not all.
