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 __________.

Answer 1

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

Answer 2

Diffusion is defined as the movement of particles across a cellular membrane due to concentration gradient. The diffusion can be passive or active, depending on the expenditure of energy.

The correct statement for the blank is:

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

The active transport can be explained as:

• Active transport is the process of movement of molecules in or out of the cell via cell membrane using energy.

• The molecules move through a region of lower concentration to the higher concentration, against the concentration gradient.

• In the given example, the movement of molecules from the inside of the cell to the extracellular fluid will always require energy.

Thus, the concentration of molecules when is lowered inside the cell than the outside of the cell.
