What is the main criterion that determines whether a cell must expend ATP to take up a solute via a transport protein?Group of answer choicesWhether the cell's membrane actively repels the soluteWhether the solute is electrically chargedThe solute's diameterThe solute's concentration on each side of the membraneWhether the solute is hydrophobic or hydrophilic
