ex 13: ammonification Flashcards
how does nitrogen exist in organisms
nucleic acid, nitrogen containing co-enzymes and proteins
how is nitrogen in proteins returned to the soil
as NH3 thorugh decompositions
steps of ammonification
proteins to ammonia
1) extracelliular hydrolytic enzymes such as proteases which make polypetides from proteins
polypep-> pep -> amino acids which are deaminated into ammonia
urea to nh4 + co2
what is the ammiia used for
lost in air, make proteins, chemoautotrophic organisms use for energy
dark brown means
LOTS OF AMMONIA
bacillus cereus and proteus vulagaris are ammonificationers
yes
why can bromomethyl blue also be used to detect ammonia
because ammonia creates a basic enfironvment and bromo is used turned pbue in this environemnt
