selective media
permits only certain organisms to grow
-
differiential media
distingueshes bacteria among morphology
-
psychrophillic

-
aerobic
grows in presence of oxygen
-
obligate aerobe
requires oxygen
-
anaeroic
grows in absence of oxygen
-
obligate anaerobe
only grow in absence of oxygen
-
facultative anaerobe
brow both anerobically and aerobically
-
aerotolerant
only grow anerobicaly but tolerates oxygen
-
microaerophillic
growth in low concentrations of oxygen
-
metabolism
sum of all chemical reactions in a cell
-
anabolism
reactions that build up
-
catabolism
reactions that break down
-
enzymes are
agents that speed up a reaction, protiens, and work to lower activaton energy
-
apoenzyme
protien portion of an enzyme
-
holoenzyme
non protien part of enzyme (cofactor) and apoenzyme
-
3 types of phosphorylation
-
oxidation
loss of electrons
-
reduction
gain of electrons
-
substrate
direct transfer of phosphate from an organic molecule to ADP
-
oxidative

-
carbohydrate catabolism functionS
- energy production and storage
- generation of chemical intermediates
