Genes have different variants, called alleles. Each individual possesses two alleles for each gene (one inherited from its father, and one from the individual's mother). Alleles can have different relations with each other, and some alleles have a stronger expression, dominating the determination of the trait in the individual.
In the case of codominance, both of the alleles are equally influential, so both of them are expressed in the individual.
The most famous example of codominance is in the A,B,O blood type alleles.
The A and B alleles are codominant, so when both of them are present in the individual, that individual expresses both A and B proteins, resulting in AB blood type.

its not the lithosphere, that's in the sky, its the crust thats broken into several large plates
Lichens are the photosynthetic organisms.
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.
