Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following can cause a protein’s shape to change?
A
A) pH
B
B) high temperatures
C
Both A and B
D
Neither A nor B
Explanation: 

Detailed explanation-1: -If the protein is subject to changes in temperature, pH, or exposure to chemicals, the internal interactions between the protein’s amino acids can be altered, which in turn may alter the shape of the protein.

Detailed explanation-2: -Answer and Explanation: Denaturation is described as the change in the structure and function of a protein. The process of altering the shape of a protein so that the purpose is lost is acknowledged as denaturation. Proteins are effortlessly denatured by heat.

Detailed explanation-3: -A protein can be unfolded, or denatured, by treatment with certain solvents, which disrupt the noncovalent interactions holding the folded chain together. This treatment converts the protein into a flexible polypeptide chain that has lost its natural shape.

Detailed explanation-4: -Some of these factors include electrostatic forces, hydrogen bonding, hydrophobic interactions, and disulfide bonds. When these interactions occur within a protein complex, a protein conformational change can occur, which enables the protein to alter its structure and shape to become functional.

Detailed explanation-5: -Similarly, if the shape of a protein is changed, it will not be able to do its job in the cell. This can happen through mutations in the DNA that change the primary structure of the protein by altering the amino acid sequence, or through heat or changes in pH through a process called denaturation.
