S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side (perpendicular to the motion of the S waves energy).
Answer:
i need help with this exact question.
Explanation:
Answer:
Essentially mRNA acts as the middle man between genetic information in DNA and the amino acid sequence of proteins.
Explanation:
messenger RNA has codons that are complementary to the sequence of nucleotides on the template DNA, which the mRNA is translating. These codons then direct the formation of amino acids through the action of ribosomes and tRNA to create proteins based on the specific DNA code translated.
Answer:
3rd option is false
Explanation:
Everything that is natural comes from Earth, For example, fruits, trees, rocks, dirt, etc.
hope this helps.
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.
