Why can ruminants recycle their urea
They have bacteria in rumen that produces enzymes (urease) to split urea back into ammonia and CO2
How is urea transported to the rumen in ruminant
Either through saliva or directly through rumen wall
Why do some animals excrete uric acid
Tend to have less access to water and need to conserve water - least toxic so least soluble
What is the least toxic form of waste
Uric acid
What are animals that excrete uric acid called
Uricotelic animals
What are animals that excrete urea called
Ureotelic
What are animals that excrete ammonia waste called
Ammoniotelic
Where can excess ketoacid be used in
Kreb’s cycle
What’s the ketoacid of aspartate
oxaloacetate
What two enzymes can indicate disease
ALT , AST
What is the name of the cycle that converts amine group to urea
Ornithine cycle
What’s transamination
Transferring an amine group from one AC to a ketoacid to make another amino acid
Where does deamination happen
Liver - hepatocytes
What is deamination
Removal of amine group from proteins
