BIOCHEM LEARNING OBJECTIVES: CHAPTER 1  (20-25 pts) 1. Describe the contributions to Biochemistry of Wholer, Mendel, Paracelsus, Miescher,  Pauling, and Watson and Crick Wholer – lab synthesis of urea  Mendel – created the laws of genetics Paracelsus – The father of biochemistry Miescher – made the discovery of DNA Pauling – used x-ray crystallography to study the structure of amides and peptides Watson and Crick – found that the structure of DNA is the Double Helix 2. List 6 elements found in bulk form and essential for life; list 4 elements in trace quanitites  in most organisms and very likely essential for life; list 4 trace elements present in some  oraganisms and possibly essential for life. - C arbon,  H yrdrogen,  O xygen,  N itrogen,  S ulfur,  P hosphorous ( CHONSP ) (6 essential) -Zinc, Potassium, Iron, Magnesium (4 trace) 3. Recognize the unique role of carbon in biomolecules; review the names and structures  of common organic functional groups - Covalently linked C atoms  form linear, branched, and cyclic backbones, giving  immense variety of compounds.

4. Name the simple building blocks (biomolecules) that compose macromolecules. - Carbohydrates, Proteins, Lipids, and Nucleic Acids. 5. Distinguish the two great classes of cells by dimension, molecular composition, and  biological function. - prokaryotic cells:  cells that lack a membrane-bound nucleus are called prokaryote;  these cells have few internal structures that are distinguishable under a microscope;

    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.
