The correct answer is Option a. The amino group is sensitive to OH-.
Explanation:
Protein denaturation means change in the structure of the amino acid. Amino acid is sensitive to various environmental factors such as pH. If the pH of the medium increases or decreases from optimum level, denaturation of protein occurs. Hydrogen bond is present in between amino acid molecules. When pH changes, hydrogen bond is disturbed and structure of protein changes.

The biogeochemical cycles move through mainly the biotic and abiotic components of the earth<span>, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. </span>
