The correct answer is B. Campylobacter
Explanation:
Guillain-Barre syndrome is a disease in which the nerves and muscles are weakened usually as the immune system attacks them which leads to changes in muscles strength, pain, and even life-threatening conditions. Although the causes of this syndrome have not been completely determined in most of the cases the condition seems to be triggered by an infection and around 30% of people who experienced an infection before the syndrome had an infection caused by Campylobacter, which suggests the syndrome is related to this type of bacteria, although it has been also linked in few cases with influenza virus, Zika virus and others. Considering this, the bacteria that is most associated with Guillain-Barre syndrome is the Campylobacter.
Answer:
The correct option is
Option (E) All the choices are membrane - bound organelles.
Explanation:
The membrane bound organelle are -
( A ) Lysosome - have digestive and destructive membranes .
( B ) Golgi apparatus - are membrane bound , and are responsible for transporting and modifying lipids and proteins .
( C ) peroxisome -
It is a membrane - bound organelle present in the cytoplasm of the cell, it plays a key role in the oxidation of some biomolecules.
( D ) Endoplasmic reticulum - is a membrane bound organelle , present in the cytoplasm , it usually has ribosomes on its outer surface , which helps in protein and lipid synthesis.
Hence,
all the mentioned organelles are membrane bound,
correct answer is ( E )
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.

Confirmatory Tests vary, and may be wrong from time to time. As time passes, the test is not as reliable as stated. If the so called "blood" is on a leather surface, blood isn't too prone to sticking to leather, so it may (or may not) be blood.
