Active Transport Definition:
Movement of a substance against a concentration gradient is called active transport.
Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Active Transport Notes:
When molecules move across a membrane from a region of lower concentration to a region of higher concentration, along concentration gradient, the process is said to be active transport. In order to achieve this movement, cellular energy is required. It can be considered that a protein pump uses energy for active transport. There are two types of active transport, primary active transport and secondary active transport. Primary active transport uses adenosine triphosphate while secondary active transport uses an electrochemical gradient. Examples of active transport include the sodium-potassium pump. It moves sodium ions to the inside of the pump and potassium ions to the outside of the pump.
