BioChem C785 module 2 quiz with complete solution

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 alpha 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 structure is not stabilized by the hydrophobic effect Alkaline phosphatase is produced by bone and liver in the human body. The amount of alkaline phosphatase in blood can help identify if a patient potentially has certain types of bone and/or liverrelated disease, including Paget disease, hepatitis, and certain types of can
