AMINO ACID METABOLISM QUIZ

Which of the following is the best described glucogenic amino acid?

Tryptophan

Lysine

Valine

None of these

TRUE ANSWER : ?
YOUR ANSWER : ?

Oxidative deamination is the conversion of an amino

acid to a keto acid plus ammonia

group from an amino acid to a keto acid

group from an amino acid to a carboxylic acid

acid to a carboxylic acid plus ammonia

TRUE ANSWER : ?
YOUR ANSWER : ?

Histidine is degraded to α-ketoglutarate and is described as a

ketogenic amino acid

keto-gluco amino acid

gluco amino acid

glucogenic amino acid

TRUE ANSWER : ?
YOUR ANSWER : ?

An example of a transamination process is

aspartate + α ketoglutarate = glutamate + oxaloacetate

glutamate = α-ketoglutarate + NH3

aspartate + hexanoic acid = glutamate + oxaloacetate

glutamate = hexanoic acid + NH3
