Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.
Explanation:
I believe the primary structure will be preserved. The secondary level of proteins is defined by patterns of hydrogen bonds between the main chain peptide groups. Therefore distorting the Hydrogen bonds disrupts the secondary structures. The primary structure on the other hand is not affected by disruption of the hydrogen bond since these structures refers to the sequences of amino acids in the polypeptide chains that are joined by the peptide bonds.
Bathroom cleaner would have the highest pH because it is an alkaline substance (pH more than 7) whereas distilled water is around pH 7 and lemon juice and vinegar are acids (pH less than 7).
Hope this helps!
The secondary structure consists of local packing of polypeptide chain into α-helices and β-sheets due to hydrogen bonds between peptide bond – central carbon backbone.
