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.

Answer:
Explanation: idk very sorry
Answer:
E. is the correct answer
Explanation:
C. An increase in A produces an increase in X.
This statement can be directly concluded from the description of the effects of hormone A on the activity of X in the problem.
A. An increase in X produces an increase in A
This statement can be concluded from the fact that A and X work in a positive feedback mechanism.
In a positive feedback mechanism, a stimulus produces a response (secretion of hormone A) which has an effect (increase in X) that increases the original stimulus. A cycle is created, in which secretion of A causes an increase of X, and the increase of X causes an increased secretion of A.
<u>To shut off the positive feedback cycle, an outside factor is required.</u>
