BCH4024 TEST 1 QUESTIONS WITH COMPLETE SOLUTIONS diffusion-limited process: - Answer-reaction rate is determined by how fast reactants collide the Protonation and deprotonation of macromolecules? - Answer-acid/base groups on surface react immediately acid/base groups deep inside may never ionize hydrogen bonds of buried helices and beta-sheets require the "conformation breathing" -local unfolding Pepsin - Answer-a digestive enzyme secreted into gastric juice, having a pH of 1.5 a...

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

The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...

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...

van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...

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...
