When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?

Energy cell harvesting is impotant. Cells need energy so they can move from one place to another and ATP helps that. ATP is consiered "energy currency" of the cell and it's useful for storing egery and helping molecules/cells move around.

Protein to move against concentration gradient requires energy. Protons go trhough a protein channel called ATP synthase which helps them move out of the mitrochonrial matrix.

helicase, i think thats it
