Biochemistry Iii

Front 1

dietary protein is degraded into what constituents

Back 1

amino acids

Front 2

what is the amino acid pool and where is it found

Back 2

combination of amino acids from diet, body proteins and liver synthesis
-found in liver and muscle

Front 3

protein turnover

Back 3

process in which body preoteins are broken down and reformed into other proteins

Front 4

what are the products of amino acid degradation? where do these products go

Back 4

NH4 excreted in urine or go through urea cycle
-acetyl CoA, pyruvate or Kreb's cycle intermediates
-forms new amino acids or used in gluconeogenesis

Front 5

what 2 substances may be formed during transamination and from what compounds respectively

Back 5

glutamate from alpha ketoglutarate
aspartate from oxaloacetate

Front 6

what is the fate of the ammonioum ion? why does ammonium ion have to be removed

Back 6

high amounts of NH4 are toxic
-they enter the urea cycle to be extrected by the kidneys into urine

Front 7

what tissue does the urea cycle predominantly occur in

Back 7

liver

Front 8

what cellular compartment does the urea cycle predominantly occur in

Back 8

cyctoplasm

Front 9

what is the starting material for the urea cycle

Back 9

ornithine

Front 10

what compound enteres into the urea cycle at the beginning?

Back 10

carbomoyl phosphate and aspartate enters at the beginning

Front 11

where are amino acids synthesized

Back 11

liver

Front 12

in animals, how does the degradation of dietary proteins contribute to the amino acid pool

Back 12

in ruminants, there is protein in the diet
in ruminants, synthesis of amino acids in the liver and GIT with the help of bacteria
