In the microbial community of the bovine rumen, the actual AG value has been calculated for glucose fermentation to acetate: CaH12O6 + 2H20 → 2CH:03 + 2H+ + 4H2 + 2CO; AG =-318 kJ/mol If the actual AG for ATP formation is 44 kJ/mol and each glucose fermentation yields four molecules of ATP, what is the thermodynamic efficiency of energy gain? Where does the lost energy go? Why is the AG not 31 kJ/mol?
