ex 10: oxidation of a carbon source by microorgansisms Flashcards
what is the most oxidized state of carbon
co2
how is carbon dioxide reduced
photosyntehsis
co2 is transformed into what
carbohydrates, which can be converted back
irgabuc compounds such as protein amino acids
why was NaoH used
as a co2 sink to measure how much co2 was obtained via aerobic respiration
indirectly can measure the amount of co2 that was evolved by determining how much naoh was used in reactin of
naoh + co2 = na2co3 + h20
determine the amount of NaOh ued
find initial moles
C=n/v
vxc = n
find the moles of hcl used
volume used x C (M) =
do final moles - initial moles
what was in the amended one
glucose
method
glucose added to amended
naoh added using a tape and applicator stick stuck to cap
not added in, just sat on top of soil
why dont we want Naoh tospill
will kill microorgansmis
determine co2
the answer from above x22mg/ml
