Which statement is true regarding active transport? group of answer choices substances can move from areas of low concentration to areas of high concentration substances can only move into cells, not out of cells substances do not require additional energy to move in and out of cell substances can only move across the cell membrane if they are water soluble

substances can move from areas of low concentration to areas of high concentration.

Explanation:

Although able to diffuse across cell membranes, the requirements of the cell for amino acids, sugars and ions cannot be fully met by diffusion alone. These substances also get into the cell by the process of active transport. It is the process by which substances move across the cell membrane against a concentration gradient.

Active transport takes place through carriers located in the membrane. Breakdown of ATP to ADP provides the energy necessary to drive the process.

The carrier binds the molecule or ion to be transported on one side of the membrane and takes it to the other side.
