What best describes the relationship between essential amino acids in humans and the number of steps in the amino acid synthesis pathway?
a)Generally, the more steps there are in the synthesis pathway, the more likely the amino acid is to be essential.
b)There is no relationship between number of steps in the synthesis pathway and whether an amino acid is essential or not.
c)All amino acid synthesis pathways are the same length, so all amino acids are equally likely to be essential.
d)Generally, the fewer steps there are in the synthesis pathway, the more likely the amino acid is to be essential.
Which of the following correctly describes the 3 amino acids that are most likely to undergo phosphorylation?
a) Serine, threonine, tyrosine
b) Cysteine, tryptophan, tyrosine
c) Serine, tyrosine, cysteine
d) Tyrosine, asparagine, serine
What is a major difference between the amino acid biosynthetic capacity of prokaryotic organisms and humans?
