Galactose→ products $\mathrm{\Delta G}=+63\mathrm{KJ}{\mathrm{mole}}^{-1}$.  This reaction is made to take place by coupling with

Galactose is a simple sugar that is normally transformed in the liver before being used up as energy. Galactose is a precursor to glucose production and need to convert to glucose. As galactose to glucose required energy, hence it is coupled with ATP (which provided energy for the conversion).
