BICH 410 (Carr) Exam #3. A modern quantitative, analytical and model-building-based approach to expand knowledge of the biochemical and biophysical properties of macromolecules found in living matter, including proteins, lipids, carbohydrates and nucleic acids. Requirement for ATP to overcome the energy barrier of membrane fusion, Passive diffusion through a biological membrane is, driven by a difference of solute concentration, Facilitated diffusion of

biological classification based on evolutionary relationships between organisms, the science of biological classification based on GROSS MORPHOLOGY, 4 most abundant elements in the human body, spontaneous processes are characterized by the transition from order to disorder, the sum of energy available to do work and unavailable to do work, gas dispersing from one chamber to the next is an example of, a reaction with positive delta H and negative delta S will, an ENDERgonic reaction with a negative delta H and negative delta S can be made spontaneous by, occurs without the addition of free energy, has negative delta G, is exergonic, living organisms maintain a _____ and they are ____ systems, the strongest non covalent interactions are, between a H atom of the water and either a N or O atom of the other molecule, molecules that have both hydrophilic and hydrophobic groups, the desire of water molecules to increase their entropy by excluding hydrophobic groups, which they must otherwise surround with highly ordered structures, how ionized are weak acids in aqueous solution, the PH of coffee is 5.6 and the PH of grapefruit is 2.6 which means the proton concentration of the coffee is, 1000X lower (10 x 10 x 10 for each PH unit), The PH at the midpoint in the titration of a weak acid with OH- is equal to, mediate transport of energy within cells, metabolic reactions, intracellular signaling, building blocks for nucleic acids (ALL OF THE ABOVE), free nucleotides are almost always associated with, by convention, nucleotide residues are written, knowledge about the tautomeric forms of the bases is necessary to understand the, H-bonding between the complementary bases, the 2 part structure with cytosine from test 1: looks like a sugar + cytosine, amino acid without a primary alpha amino group, has a side chain Pka of near neutrality so important in enzymes, would have a net negative charge at PH 12, 3.1 (add two closest Pkas and divide by 2), amide/peptide bonds (partial double bond character), elution sequence using CATION exchange resin, not useful for dissociating a multimeric protein, is specific in hydrolyzing only peptide bonds in

Biochemistry 410 Popular Study Materials from Biochemistry 410 with Carr. Homework Help. Gangliosides contain large head groups which form an inverted cone shape rather than a cylindrical shape, making close packing difficult. What is the [A]/[HA] ration when a weak acid is in a solution one pH until below it's pKa ? This enzyme form is much more efficient at binding oxygen a lower partial pressures of oxygen. Because osmotic pressure depends only on ____________, the osmotic pressure is greatly reduced by formation of polysaccharide molecules from monosaccharide molecules. Credits 4. Texas A&M University.
