    As level Biology paper 1 Help!!!

    B can not be right because kinetic energy is linked with temperature and since the temp is still increasing beyond point Q so it is incorrect Disulfide bonds are very strong and not affected by high temp, only hydrogen and ionic are broken by high temp At S, the enzyme is not COMPLETELY...
