It would have to be the third answer, "a strong thunderstorm destroys many of the nests of a bird population."

I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the
first tile from the left.
Then, the
first tile from the right is where the Leu is formed.
On the
second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them:
third tile from the right,
third tile from the left,
second tile from the left.
I believe in the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and therefore, slow the rates of glycolysis and the citric acid cycle. Phosphofructokinase is and enzyme that phosphorylates fructose 6 phosphate in glycolysis. It is an important control enzyme in the regulation of cellular respiration. It is inhibited by ATP and is an allosteric enzyme.
