WGU C785 Final Exam With Questions and Answers

WGU C785 Final Exam With Questions and Answers What is the basic structure of an amino acid? What do they look like? - correct answer amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group what kinds of bonds do each of the 3 different types of side chains make? - correct answer ionic, hydrophobic/non-polar, charged What are the 4 levels of protein structure? - correct answer Primary - linear structure, Secondary - Folded into helix or pleated sheet caused by hydrogen bonding, tertiary - 3D structure caused by side chain interactions, quaternary - 1+ amino acid chains combine = multiple subunits MUST have 1+ subunit What enviormental change breaks each type of bond? - correct answer hydrophobic - temperature change, ionic - salt or decreased pH, hydrogen - temperature, change in pH, disulfide - reducing agents what type of amino acid side chain leads to protein aggregration? - correct answer hydrophobic bonds how do environmental changes affect protein folding? - correct answer Extreme temp can cause hydrogen bonds to break apart = malformation of protein folding how do mutations affect protein structure? - correct answer Can cause structure to change. Protein loses form = loses function. May form a different protein. What is an electron? - correct answer Negatively charged atom on outer ring for bonding What is energy: - correct answer Power derived fro chemical interaction what are covalent bonds? - correct answer chemical bond, atoms share 1+ valence electrons what is an ionic bond? - correct answer bond between positive and negative what is a hydrogen bond? - correct answer weak bond betw What is the basic structure of an amino acid? What do they look like? - correct answer amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - correct answer Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - correct answer ionic, hydrophobic/non-polar, charged What are the 4 levels of protein structure? - correct answer Primary - linear structure, Secondary - Folded into helix or pleated sheet caused by hydrogen bonding, tertiary - 3D structure caused by side chain interactions, quaternary - 1+ amino acid chains combine = multiple subunits MUST have 1+ subunit What enviormental change breaks each type of bond? - correct answer hydrophobic - temperature change, ionic - salt or decreased pH, hydrogen - temperature, change in pH, disulfide - reducing agents what type of amino acid side chain leads to protein aggregration? - correct answer hydrophobic bonds how do environmental changes affect protein folding? - correct answer Extreme temp can cause hydrogen bonds to break apart = malformation of protein folding how do mutations affect protein structure? - correct answer Can cause structure to change.
