One sample of the globular protein peroxidase is hydrolyzed by heating with 6 M HC1. A second sample is denatured by treatment with acetone. a) How does the peroxidase structure change during hydrolysis? Will this change the biological activity of peroxidase? b) How does the peroxidase structure change during denatur-ation? Will this change the biological activity of perox-idase? c) Are either of these processes likely to be reversible?
