|
Denaturation is ____
|
|
chemical bonds build up and protein molecules maintain their shape
|
|
|
chemical bonds have broken down and protein molecules keep the same shape
|
|
|
chemical bonds build up and protein molecules fold to change shape
|
|
|
chemical bonds have broken and the protein molecules have unfolded and changed shape
|
Explanation:
Detailed explanation-1: -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-2: -It remains true that chemical denaturants, guanidine hydrochloride and urea, are the most generally applicable methods of completely unfolding proteins. Both of these molecules have a low molecular weight and are extremely soluble, such that 6–8 molar concentrations will denature virtually any protein.
