Catabolism Of Amino Acids Flashcards
Where does proteins breaks to amino acids?
In the intestines
Who breaker oligopeptides to amino acids?
Oligopeptidase
Whey can we use amino acids for storing or utilizing energy
When we have excessive amount of proteins or in case of starvation or diabetes
What are the proteins that are first to be degraded in case of starvation
Proteins within the muscle
Which two processes happens in the liver in case of starvation
Getting rid of non-essential proteins and breakdown of triacylglycerol
In which case we won’t breakdown amino acids?
When we would like to recycle them
Where does breakdown of amino acids to urea occure
In the liver
Which enzyme catalyses the transfer of amino group from alpha - amino acid to alphaketoglutarate
Aminotransferase
To Which amino acid alpha ketoglutarate turns when she gets an amino group
Glutamate
Which Call factor takes the amin group
PLP
What is left when the amine group is taken from the L amino acid by aminotransferase
Alpha Quito acid
What is the name of the first reaction of breakdown of amino acids
Transamination
What is the name of the step when the amine group is released from that glutamate
Deamination
Which cells can make the step of transamination
All The cells in our body
Does all the cells can make that step off transamination and urea cycle
No , only the liver because other cells Cant release ammonium via the urine and the cell can be toxicated by the ammonia
Which amino acid transport amine group from the cells of the body to the liver
Alanine
Where does the alanine cycle occur
In the muscle
To whom glutamate transport it’s amine group
To pyruvate
Which products do we get when glutamate transport it’s amine group to pyruvate
‘Alanine
Which enzyme catalyzes the reaction of transporting the amine group flight from glutamate to pyruvate
Alanine aminotransferase
Where does the glutamine cycle occur
In the muscle cells and other cells in our body
What can be the origin of free ammonia ion?
Amino acid that does not undergoes transamination and other molecules contain nitrogen lake nucleotides
In which case is there is a high activity of the urea cycle
Starvation and high-protein diet
What are the substrates off the Urea cycle
Carbamoyl phosphate and aspertate
What are the products of the urea cycle
Fumarate and urea
