catabolism - Answer the breakdown of complex molecules into smaller molecules for energy anabolism - Answer reactions that build cells which require energy communal catabolism - Answer communities participate in a joint catabolic effort to catabolize a substrate polysaccharide utilization locus - Answer a slightly different set of genes used by different xyloglucans to digest polysaccharides horizontal gene transfer - Answer the transfer of genetic material outside of binary fission;...

frederick griffith - Answers studied streptococcus pneumoniae in mice - hypothesized that bacteria could "transfer" information to each other - S strain -> host death - R strain -> not fatal - pre-killing S strains prevents illness - killed S plus live R is fatal conjugation - Answers horizontal gene transfer requiring cell to cell contact - two cells brought together by pilus on the donor - relaxase assists in DNA transfer - requires presence of transferable plasmids -> co...

microbe - Answer a living organism that requires a microscope to be seen 2 types of microbial organisms - Answer prokaryotes [cell lacks nucleus] -archaea -bacteria eukaryotes [cell w/ nucleus] -algae/plants -fungi/animals -protists 3 domains of life - Answer Bacteria, Archaea, Eukarya normal microbiota - Answer microbes normally present in and on the human body aid digestion prevent diseases by competing with pathogen microorganisms in environment - Answer recycling of n...

energy - Answer all living things need ______ to move and grow chemical reactions (catabolic and anabolic) - Answer Energy comes from: Catabolism - Answer breakdown of complex molecules into smaller ones Anabolism - Answer reactions that build cells Coupling - Answer Catabolic and anabolic reactions can be done together/at the same time in order to use the energy released from catabolism to perform anabolism the microbial buffet - Answer catabolism is nicknamed: polysaccharides...

Genome - Answer all the genetic material the organism contains Vertical transmission - Answer -from parent to offspring -same species (binary fission) Horizontal transmission - Answer -transfer of small pieces of DNA from one cell to another -different or same species 1) transformation 2) conjugation 3) transduction Transformation - Answer The process of importing free DNA into bacterial cells, cells need to be competent to do this (dead bacteria to live) Dr. Griffith - Answe...
