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.
Synthetic fabrics<span> are </span>textiles made<span> from man-</span>made fibers<span> rather than natural </span>fibers. Chemically produced fabrics<span> are </span>made<span> by joining monomers into polymers, through a process called polymerization. A </span>synthetic fabric<span>, when magnified, looks like plastic spun together.</span><span>
Natural fabrics, such as cotton, silk, and wool, are made from animals or plant based fibers. While synthetic are man made and produced entirely from chemicals to create fabrics. such as polyester, rayon, acrylic, and more. The benefits of using textiles made from synthetic fibers is that it saves the animals and plants that the fibers are based off of.
