Answer #1

G of the reaction = Products free energy values - Reactants free energy values

moles also considered

G = [ -917.3] - [ (6 x-394.9) + (6 x -237.2)] Oxygen value given Zero.

G = [ -917.3] - [ -2369.4-1423.2]

G = -917.3 + 3792.6

G = 2875.3 KJ.

Combustion of glucose (C6H12O6) is the main source of energy for animal cells: C6H12O6(s)+ 6O2(g)→ 6CO2(g)+ 6H2O(l) =ΔGrxn37°C−2872.kJ One of the most important uses to which this energy is put is the assembly of proteins out of amino acid building blocks. The Gibbs free energy of formation of one peptide bond, joining one amino acid to another, is 21/kJmol. Suppose some cells are assembling a certain protein made of 17 amino acids. (Note that the number of peptide bonds in...
