Document Summary
Electrostatic interactions are charge-charge or ionic interactions. Hydrogen bonding is a noncovalent interaction that"s primarily responsible for formation of alpha helices and beta sheets. Increase in entropy resulting from disorganization of water. Van der waals interactions are reliant on dipoles. The net charge becomes more negative (or less positive) Electrophoresis separates macromolecules on the basis of two macromolecular parameters. Enzymes catalyze reactions by: reducing the activation energy of a reaction. When an enzyme catalyzed reaction has reached equilibrium: rates of the forward and reverse reaction are the same, and there is no net change in the concentrations of substrates and products. Enzymes that catalyze the transfer of electrons are: oxidoreductases. Reactions will occur spontaneously if delta g is: negative. Enzymes will specifically bind its substrate because of: a large number of weak interactions at the active site. Blood bicarbonate can be thought of as: the deprotonated form of carbonic acid: co2 + h2o h2co3 h+ + hco3.
