An increase in ATP levels would tend to inhibit the PDH.
<h3>The oxidation of pyruvate</h3>
After the break down of glucose through the metabolic pathway known as glycolysis, the end product, pyruvate, is converted to acetylChoA in the citric acid cycle.
Pyruvate dehydrogenase (PDH) is the first enzyme of the citric acid cycle that is activated by its substrate pyruvate and inhibited by its products acetylChoA together with Adenosine Triphosphate (ATP).
This means that an increase in ATP negatively regulates the enzyme, pyruvate dehydrogenase.
Therefore, an increase in ATP levels would tend to inhibit the PDH.

Answer:
Predator-Prey Relationship
Explanation:
If the extinction of one of the species leads to an increase in the population of the other species, then the relationship must be a predator-prey relationship, because the now-extinct species was keeping the now-increasing population of the other species in check.
The enzyme amylase is the enzyme that matches up to the active site in starch to allow for its break down process. A different enzyme is needed to break down cellulose because amylase would not fit the same way into the cellulose active site in the way that the correct active site would.
