13. Unraveling the structure renders the enzymes useless, this unraveling leads to loss of its function. This process is called as 14. In others words, the enzymes are very susceptible to changes in concentrations. and 15. If a protein-digesting enzyme works in stomach's acidic pH (pH 2), would it still work in small intestine where the pH changes to 7.8? Explain, If no, please explain why not?
