RBC in hypotonic solution

Cells Burst

Mitochondroin

Endosymbiotic theory

Carl Woese

Created 3 domains based on RNA

Mesophiles

Optimal temp is always closer to maximum vs minimum

Isomerase

Rearrange atoms in molecule, create isomer of the substrate

Peroxidase

Reduces H202 with NADH

Mycobacterium

Waxy lipid covering called mycholic acid

Confocal microscope

Fluorescent dyes computer makes 3-D image

Obligate halophiles

salt loving required increased concentrations of NaCl

Ignaz Semmelwies

Handwashing

Capsule

Negative stain

Microaerophile

All organisms clustered at the top, require environments with lower levels of dioxide

Gram-positive

peptidoglycan, teichoic acides, purple (blue after acid fast)

Substrate

A specific reactant acted upon by an enzyme

Ligase, polymerase

Join molecules

Lipopolysaccharide

Aka ecdotoxin, found only in outer membrane of gram negative cells, lips A is the active component

Transferase

 Move one function group to another molecule

Alexander Fleming

Penicillin

Cell Membrane

Permeable barrier of the cell

Most Bacterial capsules are composed of

polysaccharides

Differential stains

gram acid fast, endospore

Fimbrae

Short, nonmotile, adherence

Electron microscopy

Tem- higher resolution inside the cell 2D Sem- uses scattered e-, detailed views of the surface of a specimen
