That's what happens on the normal condition. So normally, the galactose is transformed into galactose one phosphate. Then this one is transformed into this molecule and a glucose one phosphate. And then two more steps take place and ultimately we're able to break down the galactose into ATP molecules. But if both of these alleles, both of these genes are impaired in some way, that means we cannot actually create that functional galactose one phosphate urilotransphrase. And so what happens is our cells will be able to break down the lactose into these two molecules, then the galactose will be broken down or will be essentially modified to form the galactose one phosphate.
