BioChem C785 module 2 quiz with complete solution

Document Content and Description Below

Which image below shows the carboxyl group of an amino acid circled? Answer-An amino acid consists of an amino group, carboxyl group, a hydrogen and a variable side chain arranged around a central al ... pha carbon atom. The backbone of an amino acid is the entire amino acid molecule minus the variable side chain. The carboxyl group of an amino acid is shown as COO_ or COOH attached to a central alpha carbon atom of the amino acid. Which of the following statements is NOT true about the different levels of a protein structure? AnswerThe interactions between the side chains of the amino acids make up the secondary level structure of a protein Which statement reflects the role that protein structure can play in the disease process? AnswerMutation of an active site amino acid changes an enzyme's ability to bind a substrate. Aggregation of the proteins is the main reason behind many neurodegenerative diseases. Which one of the following mutations will likely cause a neurodegenerative disease? Answer-Replacing a polar amino acid with a non polar amino acid Which pair (protein interaction and technique) will likely denature a protein? Answer-Hydrogen bonds/ionic bonds: Change in pH Which one of the following statements is NOT true about protein structure and stability? AnswerProtein struc [Show More]
