Question

31. Two key amino acids in the catabolism of nitrogen atoms in the amino acids are

a. aspartate and phenylalanine

b. aspartate and glutamate

c. glutamate and serine

d. valine and alanine

32. Ketogenic amino acids cannot be converted into

a. fatty acids

b. glucose

c. ketone bodies

d. acetyl CoA

33. Which of the following is NOT true about an amino acid that is made from an intermediate of the citric acid cycle?

a. it is added to the amino acid pool

b. it is an essential amino acid

c. it can leave the cell where it was made

d. it can be used for protein synthesis

Ans 31 : b) Aspartate and glutamate

Aspartate and glutamate are the amino acids that play a key role in the catabolism of nitrogen atoms in the amino acids.

They help in contributing the nitrogen atom to the urea molecule , which is then eventually excreted by the body.
