Antigen Shape to Antibody Shape - Answer-Simple = Pocket Large = Groove Complex = Extended Surface Type of chemical bond used with antibodies - Answer-1)Electrostatic 2) Hydrogen bonds 3) Van der Waals forces 4) Hydrophobic interactions Cross reactivity - Answer-The biding site can accept a shape close enough in shape and get reaction or a stable structure Ex. Penicillin and other B-lactam Diagnostic tests for antibody/antigen - Answer-ELISA Lateral Flow test (pregnancy hCG) Immunofl...

types of lipids (purpose) correct answer: storage, structural, and signalling fatty acid chemical structure and charge correct answer: - fatty part is the carbon chain - acid part is carboxyl group (-COOH) - negatively charged which conformations of saturated fatty acids are most stable? correct answer: - anti conformation - extended conformation unsaturated fatty acids correct answer: double bonds are almost always in cis conformation which results in kinks in structure mono-...

MSE 2001 HOMEWORK CHAPTER 2 Solutions Georgia Institute Of Technology PART A. DEFINITIONS/NOMENCLATURE – (5 POINTS) 1. A type of secondary bond in which a temporary dipole induces another dipole in an adjacent atom is referred to as a van der Waals bond. 2. When the types of bonds between polymer chains are primary bonds the resulting polymer is said to be

intermolecular forces correct answer: the various forces of attraction that may exist between the atoms and molecules of a substance due to electrostatic phenomena kinetic energies correct answer: the energy required to overcome the attractive forces and thus increase the distance between particles Intramolecular forces correct answer: within the molecule that keep the molecule together Intermolecular forces correct answer: attractions between molecules, which determine many of the ...

states of matter - three primary states of matter: solid, liquid, and gas Solids - "Solids have a fixed volume and shape. The molecules that make up the solid have the shortest distance to travel until they collide with one another. This motion has been referred to as a "jiggle." Solids have a high degree of internal order; their atoms or molecules are limited to back-and-forth motion about a central position, as if held together by springs (see Figure 6-1, A). Solids maintain their shap...

What is the difference between cations and anions? - Cation is the loss of electrons, the atom becomes more positive. Anion is the gain of electrons, the atom becomes more negative. Differentiate between mass number and atomic number. - Mass number- number of protons and neutrons. Atomic number- number of protons What are valence electrons and what is their significance? - Valence electrons are electrons in the outermost shell of an atom. They are important in determining the bonds that the...

Electronegativity is larger/smaller with a greater number of electron shells. - correct answer smaller Electronegativity is larger/smaller with a greater proton number in a given period (horizontal row). - correct answer larger What is wrong, if anything, with the following statement: "When NaCl is dissolved in water, the water molecules closest to the ions will tend to preferentially orient themselves so that their oxygen atoms can interact electrostatically with the chloride ions...
