Amino acid metab (Biosynthesis)

Question 1

Asp(D/N)

Answer 1

entry into urea cycle
transamination to generate oxaloacetate and glutamate
Asparagine (N) deaminated to yield D.

Question 2

Glutamate (E/Q)

Answer 2

Oxidative deamination to alpha-ketoglutarate and ammonia

Glutamine (Q) deaminiated to yiled Glu (E)

Question 3

Threonine is degraded to..

Answer 3

acetyl CoA and Glycine

Question 4

Glycine is converted to

Answer 4

Serine which is deaminated to give pyruvate

Question 5

Tryptophan degradation to..

Answer 5

Alanine(gluco) + acetoacetate (keto)

Question 6

Aspartate(D), Asparagine(N)

Answer 6

Entry into urea cycle
Transamination to generate oxaloacetate (OAA) and glutamate
Asparagine (N) deaminated to yield D

Transamination yields aspartate from OAA
Asparagine synthetase generates Asn (N) using glutamine as amine grp donor, requires ATP

Question 7

Glutamate(E)/Glutamine(Q) breakdown/biosynthesis

Answer 7

Oxidative deamination
Transamination to generate alpha-ketoglutarate
Glutamine deaminated to yield E

Question 8

Methionine breakdown to

Answer 8

Succinyl-CoA

Question 9

Lysine degradation to..

Answer 9

2 Glutamate or acetoacetate
