1. In the degradation of amino acids in muscle NH4+ is carried to the liver for conversion into urea by:
| A. asparagine. |
| B. any amino acid. |
| C. glutamine. |
| D. either alanine or glutamine. |
| E. alanine. |
Homework Answers
In muscles, the enzyme alanine aminotransferase transfers NH4+ (obtained from the deamination of amino acids) to pyruvate to form alanine, which is then transferred to the liver. The correct answer is the option E, i.e. alanine.
A similar process in brain and some other tissues transfers NH4+ to glutamate to form glutamine, which is then used in different biosynthetic pathways or transferred to the liver.

1. Amino acids have both a three letter, and a one letter code, for example the amino acid Glycine is “Gly” or “G.” There are 20 single letter codes for amino acids, which is almost an entire alphabet. (skip any letters without a corresponding amino acid) it would make. A. For example: “Ryan Smith”, would be: “Arginine, Tyrosine, Alanine, Asparagine, Serine, Methionine, Isoleucine, Threonine, Histidine” B. Take this sequence of amino acids, and write out a sequence of RNA that could...
