Answer:

The options

A. dyspnea

B. Ataxia

C. cataplexy

D. narcolepsy

Our ANSWER IS D.

D. narcolepsy

Explanation:

It is a chronic sleep disorder which leads to excessive daylight drowsiness.

It may be due to a genetic factor and unusual signal being released in the brain as a result of absence of the brain chemical called hypocretin/orexin, which controls sleep. It is often seen as the effect of the immune system erroneously working against the production of hypocretin in thr brain.

It results in unexpected attacks of sleep, abrupt loss of muscle tone and hallucinations.

Pepsin, an enzyme that is found in the stomach of humans, functions in breaking down proteins. It is denatured as it travels to
AnnZ [28]

Answer:

A. pH

Explanation:

Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.

However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.

The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
