5.15 Urea Hydrolysis Flashcards
In the urea hydrolysis test, if the tube is pink throughout the duration of the experiment, the organism is described as demonstrating:
-rapid urea hydrolysis
The enzyme necessary to hydrolyze urea into ammonia and carbon dioxide is:
-urease
In the urea hydrolysis test, if the tube is orange at 24 hours and pink at 48 hours, the organism is described as demonstrating:
-slow urea hydrolysis
When the phenol red in the Urease Test turns pink, this indicates:
-a basic pH
In the urea hydrolysis test, if the tube is orange throughout the duration of the experiment, the organism is described as demonstrating:
-no urea hydrolysis
When the phenol red in the Urease Test turns yellow, this indicates:
-an acidic pH
In the urea hydrolysis assay, the phenol red indicator will turn pink when:
-The media has become alkaline.
Decarboxylation of certain amino acids produces ??
-urea
Urea is a primary ?? waste in the urine of many land animals:
-nitrogenous
Urea hydrolysis produces ?? that can be used by some organisms as a nitrogen source:
-ammonia
pink=
orange or yellow=
-rapid urea hydrolysis
-no urea hydrolysis
