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.

The correct statement is that the concentration of acetylcholine will be inhibited by enzymes and can cause several diseases as follows:

Alzheimer's disease-related to damage to brain cells,
memory loss,
and thinking ability.

How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.

<h2>Further Explanation </h2>

Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.

There are several side effects of the acetylcholine drug, which are as follows:
