1. When a protein is ingested & encounters the acidity of the stomach (pH 1.0), its tertiary structure will be disrupted. A non covalent interaction that will be broken will be salt bridges within the protein because the _______ group (pKa 3.5) will become protonated. This will result in an excess of ______ charges on the protein and the electro-repulsion will further disrupt structure. A) Amino; Negative B) Amino; Positive C) Carboxyl; Negative D) Carboxyl; Positive correct answer: D) Ca...

CBE 555 Question and answers 2023/2024 verified to pass "Which of the following statements are correct? Explain your answers. A. A DNA strand has a polarity because its two ends contain different bases. B. G-C base pairs are more stable than A-T base pairs." - correct answer "A. False. The polarity of a DNA strand usually refers to the orientation of its sugar-phosphate backbone: one end contains a phosphate group, the other end contains a hydroxyl group. B. True. G-C: 3 H-bonds vs A-T: o...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - CORRECT ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the ...
