BIOC0001 - PRACTICAL B (TRANSAMINATION) EXAM
QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS
VERIFIED LATEST UPDATE
Do animals store excess amino acids?
No.
What happens to excess amino acids?
They undergo deamination.
Describe the general deamination process.
The amine group is removed and converted to ammonia with the remainder of the
amino acid, mostly carbon and hydrogen, being used in other metabolic reactions.
The ammonia is excreted in the urine as urea.
What is the function of transaminases?
Transfers amino groups between amino acids and oxo-acids.
What is an oxo-acid? What is another name?
A compound that contains H, O and one other element with at least one H-bond to
oxygen capable of dissociating.
Keto-acids.
What is the function of glutamate dehydrogenase?
Catalyses the oxidative deamination of glutamate.
