Question

Each of the following is a noncovalent interaction EXCEPT: a carbon-hydrogen bond. a van der Waals interaction. a hydrogen bond. an interaction between -NH_3^+ and a water molecule the interaction between an amino and a carboxylate group Small ions in biological fluids: have no effect on the interactions between oppositely charged macroions. tend to cluster around macroions of the same charge. have large effects on pH. encourage strong electrostatic interactions between oppositely charged macroions at low ionic strengths. encourage strong electrostatic interactions between oppositely charged macroions at high ionic strengths The Delta G degree of a reaction: is not related to the equilibrium constant. will change if the concentration of reactants and products are changed. can be used to calculate whether a reaction is thermodynamically favorable under defined non-standard conditions. will change if the temperature of the reaction is changed can predict whether

Explanation / Answer

1) non-covalent interaction in this type bond not involve the sharing of electrons, but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule.

answer is carbon-hydrogen bond.

2) encourage strong electrostatic interactions between oppositely charged macroions at low ionic strengths.

3) deltaG0 = -RT ln [K]

[K] = equilibrium con.

delta G0 will change if the tempertaure of reaction change

4)A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group.

nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.

answer is phosphate group.

5) answer is option A
