Unformatted text preview: REVIEW GUIDE FOR BIOG 110 PRELIM #1 You have a number of resources to help you prepare for Prelim #1. Each of the following is posted on the BioG110 Blackboard site. o Potential Prelim essay questions written by Professor Wayne (recall 1 of the posted questions will appear on the Prelim) o The pre & post lecture questions written by Professor Wayne – Recall and large portion of the exam will be composed of these questions o Lecture Note summaries and this review guide written by Dr Balko o Practice prelim questions written by Allen [CLT & BioG010 Tutor] o Practice Prelim written by Allen [CLT & BioG010 Tutor] At this point, you should use the ppts and lecture notes as reference sources (much as you would a text book) to help you find the answers for all the questions listed in the above files. The remainder of this review guide will serve as an outline of key terms and concepts you should know. The “transcribed” lecture note summaries (mentioned above) will be a good source for key concept summaries. Term & Concepts You Should Know: 1. Living organisms are characterized by what physico-chemical and biological features?-moves by internal forces, takes up small molecules and synthesizes large organic molecules that it uses to grow, transforms one kind of energy into other forms of energy, often by "burning" organic molecules using oxygen, generates electrical energy, responds appropriately to the environment, and reproduces with near perfect fidelity 2. What are Amino Acids found in under what prebiotic conditions can they be formed?-they are found in proteins-Stanley Miller created an experiment in which he created amino acids by mimicing prebiotic conditions which contained hydrogen, methane, ammonia, and water (carbon and nitrogen) 3. Why are proteins so important? What are their different functions? -enzymes, help reactions take place 4. Why are Nucleic Acids so valuable as the “keepers” of the genetic code? Why them and not one of the other groups of organic compounds.-because they are made up of polymers that have specific order of the different subunits 5. Where did the oxygen in the Earth’s atmosphere originate? AND, why is this so important to the diversity of life we now see on Earth (hint: think types of Cell Respiration and benefits of each type).-stars 6. What is the Vitalist & Materialst views of life [be able to distinguish between the two].-materialist=biology and physics are the components of life-vitalist=a life force 7. Why was Pasteur’s work pivotal to our knowledge that life does Not arise form spontaneous generation? Know his experiment & conclusions.-repeated Spallanzani's work with his famous swan-shaped flasks that allowed air to pass through but not microbes and no microbes were generated in the broth thus disproving Spallanzani's theory of spontaneous generation 8. You have heard about Walter B. Cannon throughout the course this semester—why is he so important?...
