Answer:
D is incorrect. Took the quiz. The most acceptable answer is either A or C
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.
Its stored in the chloroplasts
Answer:
D. stabilizes the position of the kidneys by holding them in their normal position
Explanation:
Adipose tissue is a type of connective tissue and is therefore called by some adipose connective tissue. As we saw in the article “Connective Tissue Cells”, adipose tissue is made up of adipose cells, also called adipocytes. Fat tissue specializes in fat storage and is found well below the skin.
Some of our internal organs like kidneys and heart have a layer of adipose tissue lining them. This layer of fat around the organs gives them greater protection against mechanical shock. In addition, in the kidneys, adipose tissue fills the voids between other tissues and helps keep these organs in their normal positions.
