The bacterium responsible for gastric ulcers, Helicobacter pylori, survives the acidic pH of the stomach surprisingly well. It d
Olegator [25]

Answer:

H. pylori uses the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2), where NH3 can act as a buffer to the acidic solution in the stomach.

Explanation:

<em>H. pylori</em> is a bacteria that has the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2). The compound of interest here would be ammonia, or NH3. NH3 is a base, although relatively weak to other stronger bases, which means it has a pH above 7. In the stomach, the pH is acidic, or below 7. By synthesizing ammonia, <em>H. pylori </em>is able to buffer the stomach solution in a manner so that it isn't entirely acidic, but more toward the basic side, thereby allowing for its survival.

_____ is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step
hjlf

Answer:

Option C) Feedback inhibition

Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.

Explanation:

Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.

For example:

The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis

What happens as the reaction rate continues to rise
e-lub [12.9K]

Answer:

increasing substrate concentration,

Explanation:

The reaction rate still increases with increasing substrate concentration, but levels off at a much lower rate. By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases.
