Lac y encodes for Galactoside permease that promotes the entry of lactose into the cell. lac a encodes for transacetylase, that adds an acetyl group to the lactose molecule making ...

... vertebrates. maybe because of this they do not need insulin or an insulin like hormone. also, they may posses a different protein than the GLUT2 permease which does not require help. Remember that the GLUT1 permease for glucose humans have in their brain keeps it's speed constant regardless of ...
