The electron transfer potential of nadh and fadh2, relative to o2, drives oxidative phosphorylation and atp synthesis. oxidation of nadh occurs by the following reaction: 0.5 ozut nadh + h+ = h2o + nad+ a. calculate ae'o and ag'' for the oxidation of nadh. hint: you'll need to identify the two half reactions for the reaction above. b. what is ag'' for the synthesis of atp from adp? c. using your results from parts (a) and (b), explain how the electron transfer potential of nadh drives atp synthesis.

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)

explanation:

a polar bond is formed when electrons are shared unevenly between atoms
