Active Transport

• Active transport is the movement of molecules from an area of low concentration to an area of high concentration against a concentration gradient. This requires energy
• Examples of active transport are the movement of glucose into the cell from the blood
• Active transport requires energy from respiration to move substances against their concentration gradient.
• Active Transport is when substances move against their concentration gradient with energy input
• Active transport can be used by plant roots to absorb minerals like potassium and calcium which are essential for growth.
