__________
Glucogenic - CORRECT ANSWER - __________ amino acids are metabolized
intermediates of the TCA cycle and are used in the process of GNG
cannot - CORRECT ANSWER - Essential amino acids are required in the diet and
can/cannot be synthesized in the body
can - CORRECT ANSWER - Nonessential amino acids can/cannot be synthesized in the
body.
1) Used for protein synthesis and degredation with ATP + ubiquitin moeity
2) substrate for nitrogen containing compounds - neurotransmitters /nucleotides
3) Carbons from AA used as substrate for FA synthesis and GNG
4) disposal and metabolism of amino group through synthesis of urea in urea cycle - CORRECT
ANSWER - Name 4 things amino acids are used for.
liver - CORRECT ANSWER - Amino acids travel to the _________ where they are broken
up into carbon and nitrogen containing compounds
fatty acids; glucose - CORRECT ANSWER - carbon compounds derived from amino acids
are used in the liver to produce __________ or ___________.
Urea - CORRECT ANSWER - Nitrogen compounds derived from amino acids are
disposed of in the liver through the _________ cycle
, muscle - CORRECT ANSWER - 60% of branch chain amino acids are metabolized in the
________. (hint: 20% come from portal circulation
Alanine; Glutamine - CORRECT ANSWER - In the FASTED state the two circulating
amino acids are _________ and _________.
cortisol - CORRECT ANSWER - Alanine and Glutamine come from __________
mediated protein catabolism in the skeletal muscle
GNG - CORRECT ANSWER - Alanine and Glutamine enter the liver and used for
production of glucose through ____________________.
alanine shuttled from skeletal muscle --> enters liver where it's transaminated to pyruvate -->
amino group enters urea cycle and carbon group used for glucose - CORRECT
ANSWER - Describe the alanine-glucose cycle
The alanine-glucose cycle is used for the transport of nitrogen from the skeletal muscle to the
liver and glucose back to the skeletal muscle as an oxidizable substrate. - CORRECT
ANSWER - What is the alanine-glucose cycle used for?
Nitrogen - CORRECT ANSWER - Alanine and Glutamine are the major non-toxic carriers
of ____________
pyroxidal phosphate - CORRECT ANSWER - Aminotransferases are enzymes that
requires the cofactor ____________ ____________ to help in the transfer of nitrogen from an
AA to an alternative keto acid
nitrogen - CORRECT ANSWER - Aminotransferases do not free ammonia, but will
transfer the nitrogen
