The dissolution of nonpolar molecules in water is unfavourable because of the large decrease in entropy resulting from clathrate formation, even though the process is exothermic (dH < 0) But unfavourable dG > 0.

During hydrophobic interaction, the non-polar molecules come together, releasing some of the ordered water molecules in the clathrate structure and thus increasing entropy.

This is a thermodynamically favourable process (dG < 0), even though it is endothermic (dH > 0) because more hydrogen bonds are broken than are made.

When blood glucose rises above 5 mM, hexokinase IV activity increases, but hexokinase I is already operating near Vmax and cannot respond to an increase in glucose concentration.
