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 and Explanation:
There are four major roles of muscles that provide the movement that are given bellow.
AGONIST : They are also known as prime movers it provides force to complete the movement.
example : flexion of elbow
ANTAGONIST : They oppose the movement which was produced by agonist
example : extension of elbow by triceps
NOTE : They also slows down the movements
SYNERGISTS : Their main role is to stabilize the joint in which moment take place they also help in performing the movement to agonist.
FIXATORS : Their main role is to stabilize the origin of agonists and stabilize the joint
example : Rotator cuff muscles
Ice can cause hypothermia.
Ice can cause vasoconstriction
Ice can reduce blood flow to the burned area.
<h3>What are the reasons to avoid use of ice on burned body parts ?</h3>
Ice can result in hypothermia, which reduces blood flow to the burned area and causes the burned part to cool excessively. Ice has the potential to shrink the blood vessels supplying injured skin, resulting in a reduction in the amount of blood and oxygen delivered to the area.
- Applying ice does not stop further tissue damage; instead, it reduces blood flow, delaying the healing of the wound. Ice actually reduces blood flow owing to vasoconstriction, rather than increasing it, to the burned area.
