Question

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it

Answer 1

the concentration of the solute is lower inside the cell than outside it

Step-by-step explanation:

This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.

This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
