ADP and Pi have A) More resonance stabilization B) Less electrostatic repulsion C) A greater degree of ionization D) A greater ability to isomerize E) A greater degree of hydration than does ATP 7) During glycolysis the following reaction requires NAD+: A) Alcohol dehydrogenase B) Glyceraldehyde:3-phosphate dehydrogenase C) Lactate dehydrogenase D) Pyruvate dehydrogenase E) All of the above 8) NAD+ A) Accepts 2 electrons and 2 hydrogen ions B) Accepts 2 electrons and 1 hydrogen ion C) Accepts 1 electron and 1 hydrogen ion D) Transfers electrons in reductive biosynthesis E) In its oxidized form is NADH

Explanation / Answer

5-D) polarity and hydrogen bonding capacity

water is a polar molecule due to which other polar substances are allowed to dissolve in water very easily, hydrogen binding is responsible for the unique solvent capacity of water. Because of its polarity and hydrogen bonding capacity water is known as the universal solvent means it can dissolve different type of molecules

6-d) a greater ability to isomerize

the factors that contribute to the high phosphoryl group transfer of ATP are resonance stabilization, stabilization due to hydration, a greater degree of ionization and electrostatic repulsion

7-b) glyceraldehyde 3- phosphate dehydrogenase

NAD+ is used as a cofactor in the conversion of glyceraldehyde 3-phosphate into 1, 3 bisphosphoglycerates which are catalyzed by glyceraldehyde 3-phosphate dehydrogenase

8-B) accepts 2 electron and 1 hydrogen ions

NAD+ accepts 2 electrons and one hydrogen ions and becomes reduced to NADH. The NADH donates its electrons to the electron transport chain(ETC) which is ultimately donated to the oxygen(the final electron acceptor) generating a large amount of ATP
