Gateway Technical College BIO 806-177 BIOCHEM QUIZLecture 1 For Midterm 1 Lecture 1 : Thermodynamics 1)Which of the following is NOT an example of a biopolymer? phosphatidyl serine Starch Myoglobin DNA Which of the following statements is generally TRUE? Eukaryotic cells are larger and less compartmentalized than prokaryotic cells Eukaryotic cells are smaller and more compartmentalized than prokaryotic cells Eukaryotic cells are larger and more compartmentalized than prokaryotic cells Eukaryotic cells are smaller and less compartmentalized than prokaryotic cells Which of the following organelles is NOT present in animal cells? Lysosome Mitochondrion Nucleus Chloroplast Which of the following is always TRUE about a reaction that happens spontaneously? Change in G is negative Change in H is negative Change in S is positive Change in H is negative and change in S is positive As ice melts into water, how does entropy and enthalpy change? Entropy increases, enthalpy decreases Entropy increases, enthalpy increases Entropy decreases, enthalpy increases Entropy decreases, enthalpy decreases Which of the following statements is TRUE about open systems? Only reactions with positive change in S are spontaneous A reaction with change in G = -20 kj/mol will always proceed faster than one with change in G = -10 kJ/mol Reactions with a negative change in S may be spontaneous A reaction that occurs spontaneously at T = 273K will occur spontaneously at T=300K Which of the following do you expect to have the highest entropy? Ammonia (NH3) gas Liquid Ammonia Solid Ammonia All of the above have the same entropy
