which bonds are the last to break when an enzyme is heated?

A)disulphide B)hydrogen C)hydrophobic interactions D)ionic

I don't the correct answer
I don't if I should think of it from a chemistry perspective ie just look for the strongest type of bond and that will be the last one to break, or an "enzyme structure breakage sequence perspective", ie the quaternary structure has all the ansr choices except hydrophobic, but the tertiary has hydrophobic and it breake after the quaternary so it should break last😕
please help

my guess would be ionic...coz strong is still strong!!!

i would say disulphide bond. enzymes are proteins so they do contain disulphide bond but they also have hydrogen and ionic bond as well. so what is the answer?

B, C and D are non-covalent bond. Thus the answer is disulfide bond since it's covalent bond. :😉

FYI: You can use metacarphol (am I spelling right?) or detergent to break disulfide bond!!!

prob disulfile bonds... (covalent)
