There is a larger number of a hydrophilic molecules on the outside of a cell than on the inside. Identify the conditions that could equalize the intracellular and extracellular concentrations of this molecule. Select all that apply. placing carrier proteins in the membrane placing only intracellularly – directed pumps in the membrane placing intracellularly directed and extracellularly directed pumps in the membrane not inserting any transport proteins in the membrane Which of the conditions would be the most metabolically efficient way for a cell to equalize the intracellular and extracellular concentrations of this molecule? not inserting any transport proteins in the membrane placing only intracellularly – directed pumps in the membrane placing carrier proteins in the membrane placing intracellularly directed and extracellularly directed pumps in the membrane
