Define Active Transport [exclusive] -

In simple terms, is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration.

Active transport is the energy-dependent movement of molecules from a low-concentration area to a high-concentration area, facilitated by protein pumps that work against the natural tendency toward equilibrium. define active transport

Imagine a crowded concert venue.

Your cells produce carbon dioxide and hydrogen ions (acid). If these built up, they would kill you. Even if the blood outside the cell is already slightly acidic, active transport pumps the H+ ions out to keep the cell’s internal pH at a safe 7.2. In simple terms, is the movement of molecules

Roots use active transport to pull minerals and salts out of the soil, even when the concentration in the soil is much lower than inside the plant.
