MAP-UA 310 NATURAL SCIENCE II: MOLECULES OF LIFE FALL 2011 STUDY GUIDE FOR FINAL EXAM 1. EXAM GUIDELINES The final exam for the course is scheduled for: TUESDAY, DECEMBER 20 4:00 – 5:50 p.m. Silver 206 The exam must be written in PEN AND NOT PENCIL . Please bring a pen to the exam (plus a back-up). You will NOT need a calculator for this exam. The exam will be organized in the following way: Roughly 50% of the points will be based on course material after Midterm Exam 2 (Chapters 18, 19, and 20 plus Lab 10). This study guide collects all the study questions for the final section of the course. Roughly 50% of the points will be based on material from earlier in the course . You should use the study guides for Midterm 1 and Midterm 2 to review this course material. No questions on the earlier lab projects (Labs 1 – 9) will be included on the exam. Material in the textbook chapters that was not discussed in class will not be in the exam. Each section will contain multiple questions of DIFFERENT FORMATS : Multiple choice Short answers Drawings (e.g., molecular structures, biological processes, etc.) Applying your knowledge to new examples (e.g., figuring out how a certain drug works, designing a new enzyme inhibitor based on the principles of enzyme function, etc.) You will be provided with the following reference information: periodic table electronegativity values of different elements. genetic code table 1

2. STUDY QUESTIONS Guidelines These questions should be used to guide your studying for the course. Some questions address foundational knowledge and concepts, with important scientific terms highlighted in bold . Other questions ( written in italics ) identify certain skills that you should develop throughout the course. I recommend that you review these questions each week to ensure that you are keeping up with the course topics. It is also beneficial to write short answers to the questions in the spaces provided. You can use these answers as a study guide when preparing for exams. These questions are intended for your benefit and they do not need to be submitted as a class assignment. The following study questions have been reorganized according to textbook chapter . CHAPTER 18: Chemical Reactions and Catalysis Nitrogen Fixation What is “nitrogen fixation? Why is it chemically difficult to obtain nitrogen atoms from N 2 gas in the air? -N 2 molecule contains a very strong N N double bond, which is difficult to break apart. Because of its bonding properties, N 2 is not chemically reactive under normal conditions. The solution to this problem was provided by Fritz Haber, a chemist working in Germany at the turn of the early 20 th century (Figure 18.2). Haber wanted to figure out the optimal chemical conditions for reacting nitrogen and hydrogen gases to generate ammonia (NH 3 ). This is a reversible chemical reaction described by the following equation: N 2 (g) + 3 H 2 (g) = 2 N H 3 (g) The reaction is called
