Nitrogen released from the breakdown of proteins is used in the synthesis of urea, which is excreted by the kidneys in the urine.
- The urea acid cycle transforms the nitrogen waste released during this process into urea, which is then excreted in the urine.
- Amino acids can be converted into energy during famine and go via the Krebs cycle.
- Muscle protein is broken down into amino acids while fasting, some of which are partially oxidized to provide energy.
- These amino acids are split up into alanine and glutamine, which are released into the circulation together with other amino acids.
- Several tissues, notably the stomach and kidney, oxidize glutamine, converting some of its carbons and nitrogen to alanine.
- The liver is where alanine and other amino acids are processed into glucose and ketone bodies and nitrogen.

Answer: Rare X-linked recessive
Explanation:
In humans our biological sex-determination is based on a pair of sex chromosomes namely, XX in females, XY in males. The genes on our X chromosome are X-linked. and have special patterns of inheritance due to their presence in contrasting numbers in males (XY, 1 X chromosome) and females (XX, 2 X chromosomes); thus they are more common in genetic males.
The observed trait is X-linked, and given that only half the sons are affected, the trait is recessive and carried by the heterozygous mother -heterozygous alleles are two variants of the allele at the same gene locus. The Y chromosome inherited from the father does not carry the gene, thus there is no normal copy available. The incidence for its inheritance is at 50% as the mother has two X hromosomes, one normal, and one carrying the trait.
