Question

Select the correct answer from each drop-down menu. Compared to its surroundings, the concentration of solutes is low inside a cell. So, the cell is with respect to its surroundings. A particular solute in this cell uses energy for its transport from the cell to its surroundings. This type of transport is called .

Answer 1

When the concentration of a certain solute is low inside the cell with respect to the cell's external environment, then the cell performs active transport of the solute from the cytoplasm with a low concentration of solute within the cell to the cell's external with a high concentration of the solute. This process of active transport requires the need of energy in the form of ATP to drive the pumps that are present on its cell membrane.
