WGU C785 BIOCHEMISTRY EXAM [QUESTIONS AND ANSWERS] [GRADEDC A 2023/2024] 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 ...

Hydrocarbons are ... Correct Answer-nonpolar, hydrophobic 5 Functional Groups Correct Answer-amino, hydroxyl, sulfhydryl, phosphoryl, carboxyl, methyl Amines Correct Answer-nitrogen joined to at lesat one alkyl group amide Correct Answer-have a carbonyl group between the nitrogen and R group functional group characteristics Correct Answer-- contain electronegative atoms (O,N,S) - usually electrically charged or polar - make organic molecule amphiphathic - create multifunctional mo...

True or false: observations allow scientists to draw tentative explanations called hypotheses. -false -true - ANSWER true The negatively charged components of atoms are referred to as: -anions -electrons -neutrons -protons -cations - ANSWER electrons Which one of the following contributes to the measurement referred to as atomic mass? -protons and electrons -protons and neutrons -neutrons only -electrons and neutrons -protons, electrons, and neutrons - ANSWER protons a...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - 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 development of sickle ce...

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

Which of the following corrctly matches the amino acid with its three-letter abbreviation? A) tryptophan: try B) isoleucine: iso C) cysteine: cys D) asparagine: asn E) valine: van correct answer: C) cysteine: cys Which hydrophobic amino aicd containes sulfur in its side chain? A) alanine B) valine C) phenlyalanine D) proline E) methionine correct answer: E) methionine Which amino acid is achiral (not chiral)? A) alanine B) valine C) glycine D) proline E) methionine c...

The Scientific Method - A logical, systematic approach to the solution of a scientific problem. What is science? - The systematic approach to answering questions; step by step process that is logical and rational by collecting data thru experimentation steps of scientific method - 1. observation 2. question 3. hypothesis (that is testable) 4. test/experiment 5. conclusion conclusion of scientific method - accept hypothesis OR reject hypothesis and make a new hypothesis 2 groups of an e...

d. one of the atoms sharing electrons is much more electronegative - correct answer A covalent bond is likely to be polar if _____ a. it is between two atoms that are both very strong electron donors b. the two atoms sharing electrons are equally electronegative c. it is between two atoms that are both very strong electron acceptors d. one of the atoms sharing electrons is much more electronegative e. the two atoms sharing electrons are of the same element e. is weak - correct answer...
