AMINO ACID METABOLISM QUIZ

A person with phenylketonuria cannot convert

phenylalanine to isoleucine

phenylalanine to lysine

phenol into ketones

phenylalanine to tyrosine

TRUE ANSWER : ?
YOUR ANSWER : ?

A glucogenic amino acid is one which is degraded to

pyruvate or citric acid cycle intermediates

None of these

keto-sugars

either acetyl CoA or acetoacetyl CoA

TRUE ANSWER : ?
YOUR ANSWER : ?

Transamination is the process where

carboxyl group is transferred from amino acid

polymerisation of amino acid takes place

None of these

α-amino group is removed from the amino acid

TRUE ANSWER : ?
YOUR ANSWER : ?

An example of the oxidative deamination is

aspartate + α-ketoglutarate = glutamate + oxaloacetate

glutamate = α-ketoglutarate + NH3

glutamate = hexanoic acid + NH3

aspartate + hexanoic acid = glutamate + Oxaloacetate

TRUE ANSWER : ?
