it is proposed that ( a ) ppi may replace atp in the formation of fructose-1-6-p2 when the organism is grown on glucose and ( b ) when the organism is grown on lactate or glycerol the conversion of fructose-1,6-p2 to fructose-6-p during gluconeogenesis may occur by phosphorolysis rather than hydrolysis .
