Exam1: Starch, Cellulose, carb polymers/polymers of glucose s,c· NOT true about systems biology- Does not require interdisciplinary teams · make up approximately 96% of living matter- carbon, hydrogen, nitrogen, oxygen · (NH 3) - Each hydrogen atom has a partial positive charge ·polar covalent bond H-O ·Water's high specific heat is absorption and release of heat when hydrogen bonds break and form · Desert rabbits are adapted to the warm climate because their large ears aid in the removal of heat due to the high heat of vaporization of water ·Carbon atoms can be covalently attached to form linear chains, branched chains and rings ·hydrocarbons are not soluble in water because the majority of their bonds are nonpolar covalent carbon-to-hydrogen linkages ·SH is a functional group that helps stabilize proteins by forming covalent cross- links within or between protein molecules·COOH is an acidic functional group that can dissociate and release H+ into a solution·NH 2 is a basic functional group that can accept H+ and become positively charged·Polymers of polysaccharides, fats, and proteins are all synthesized from monomers by the removal of water (dehydration reactions) ·A molecule with the chemical formula C 16 H 32 O 16 is probably a carbohydrate ·Lactose, a sugar in milk, is composed of one glucose molecule joined by a glycosidic linkage to one galactose molecule is lactose classified as a disaccharide ·A molecule with the formula C 18 H 36 O 2 is probably a lipid ·Triacylglycerol is a lipid made with three fatty acids and glycerol · hydrocarbon chain with COOH is unsaturated fatty acid ·cell membranes are made of Phospholipids ·The 20 different amino acids found in polypeptides exhibit different chemical and physical properties because of different side chains (R groups) · The bond from dehydration is a peptide bond ·negatively charged amino acid is a Glutamic acid · secondary structure of a protein maintained by hydrogen bonds ·tertiary structure of protein maintained by disulfide bonds·protein molecule that assists in the proper folding of other proteins is a chaperonin ·nucleotides have a nitrogenous base, a phosphate group, and a pentose sugar · In the double helix structure of nucleic acids, cytosine hydrogen bonds to guanine, adenine to thymine ·RNA- adenine to uracil, cytosine to guanine ·You are studying a DNA-binding protein. What amino acid would you most likely find in the parts of the protein that interact with DNA- Arg · Exam2: The smooth endoplasmic reticulum functions in synthesis of Lipids · the following are prokaryotic cells Bacteria ·components of cytoskeleton are Microfilament, Microtubule, Intermediate filament, but not Gated ion channel ·In which cell would you expect to find the most tight junctions Epithelial cells lining the digestive tract, but not Muscle cell in the thigh muscle of a long-distance runner , Pancreatic cell that manufactures digestive enzymes ,

    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.
