Unformatted text preview: AP Biology Chapter 4 Objectives Anette Paez Name _________________________ Again, this chapter is a review of previously covered material. We will be moving through the material very quickly, please see me for extra assistance if needed. 1. Why is organic chemistry so important in the study of biology? All living things are made of cells, which are built into organic compounds using carbons (DNA, RNA, Proteins, Carbs, Lipids) 2. Why was the Urey-Miller experiment so important? Similar chemical reactions he conducted in his experiment, may have set the stage for the origin of life on Earth (synthesis of some organic molecules) 3. What is special about carbon that makes it the central atom in the chemistry of life? The electron configuration of carbon gives it covalent compatibility with many different elements (Versatile building with 4 bonds) 4. Use the diagram below to label and contrast the three types of isomers. structural isomers geometric isomers enantiomers Page 1 of 2 5. Create a table below: after each functional group – draw the structure, name the compound, write and example and note the functional properties – (doesn’t this look like great quiz material?) a. Hydroxyl Hydroxyl Group- Compounds C Alcohols polar; can form H bonds with water OH H b. Carbonyl aldehyde Aldehyde end Found in sugars c. Carbonyl ketone Ketone middle Found in sugars d. Carboxyl Carboxylic acids acidic properties, source of H(pos) e. Amino amines acts as a base; picks a pH(pos) from solution f. Sulfhydryl Thiols Stabilizes protein structure g. Phosphate Organic Phosphates Contributes neg. charge; Can react with water, releasing energy (ATP to ADP (energy)) Page 2 of 2 ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
