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.
Answer:
If oxygen supply is depleted the muscle cells will respire anaerobically and release lactic acid and energy.
The accumulation of lactic acid , results in a pain in the muscles of the athlete.

Answer: Behavioral genetics
Explanation: This concept indicates that our genes influence our environment and in return, the environment influences our genes. Behavioural genetics has therefore expressed gene-environment interactions on the behaviour of an individual.
