There is no option provided related to the experiment that is conducted to test the effect of pepsin under various conditions. However, answering the question will be easier if students understand the conditions under which pepsin works best. Pepsin will be active and work best in acidic conditions with pH values ranging from 1.5 to 2.5.
<h3>Why would pepsin work better in acidic environments?</h3>
Pepsin is a digestive enzyme that aids in the digestion of proteins contained in food. Pepsin is secreted by gastric chief cells as a dormant zymogen known as pepsinogen. Parietal cells in the stomach lining release hydrochloric acid, which lowers the stomach's pH. Pepsin is activated by a low pH, 1.5 to 2, and works optimally at pH 1.8 since the carboxylic acid group, which is located on the amino acid in the active site of pepsin, must be protonated, or connected to a hydrogen atom. At low pH, the carboxylic acid group protonates, allowing it to catalyze the chemical process of chemical bond breakdown.

Lungs = respiration, provides oxygen to the blood.
heart = arteries, pumps blood.
Answer:
The technique is called the Heimlich maneuver, or abdominal thrusts. Abdominal thrusts lift your diaphragm and expel air from your lungs. This causes the foreign object to be expelled from your airway. And The Heimlich maneuver is a lifesaving first aid technique. It is preformed when someone is choking and unable to breathe. The maneuver consists of a person wrapping their arms around the other, using the technique to thrust a piece of food or foreign object out of their throat.In order to show others that you are chocking, hold your hands around your throat. Make sure to educate your family and friends about this signal. It is important that they know what to do if they are chocking and it is important for them to know what to look for if someone else is chocking.
