..... The concentration of three different aminoacyl-tRNA synthetases, associated with three different amino acids, are found in much lower than normal concentrations in the cytosol of an animal cell. In your own words, describe how this may impact the rate of A) translation, and B) the citric acid cycle. Explain your reasoning for each. Please clearly label your responses as A) and B).

An aminoacyl-tRNA exhibits which one of the following characteristics? A. It is produced by a synthetase that is specific for the amino acid, but not the tRNA B. It is composed of an amino acid esterified to the 5’ end of the tRNA C. It requires GTP for its synthesis from an amino acid and a tRNA D. It contains an anticodon that is complementary to the codon for the amino acid Concerning generation of ATP from glucose during glycolysis...
