A polypeptide chain has a large percentage of acidic and basic amino acids in it. The R groups of these amino acids form ionic interactions, which helps the protein to maintain it's structure. This particular polypeptide works well under an optimum pH of 7. Ignoring effects of strong acids and bases on peptide bonds, what will happen to the tertiary structure of the protein if you move it stomach acid, which has a pH of 1-2. Why?

The tertiary structure will be destroyed

Explanation:

when the above mentioned polypeptide is placed in the stomach, which has a low pH, the structure and stability of the protein changes. decreasing the pH by adding an acid

Causes the ionic attraction to disappear, and the protein shape unfolds. denaturation of protein occurs. Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Therefore the tertiary structure of protein is destroyed

they both have a y in them

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
