active transport
Active Transport
the cell membrane
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.

Active transport is the movement of a substance against its concentration energy.

The transport of a substance across the cell membrane against its concentration gradient is called active transport.
the cell membrane
Electrochemical gradient is used to move substances through a membrane in active transport.
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.
