Yes, any form of active transport uses energy.
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Energy, versus passive in which energy is not used.
Energy, versus passive in which energy is not used.
Active transport uses energy in the form of ATP. Active can force electrons against the electron gradient as in the electron transport chain. Passive transport does not use energy and an example of passive transpost is osmosis.
Energy, versus passive in which energy is not used.
ATP is often used as the source of energy during active transport.
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
The source of the energy used in active transport is the electrochemical gradient. Another possible source of energy for active transport is the breakdown of ATP molecules.

in the cells
ATP supplies the energy for active transport.
A secondary active transporter. An example is Na+/glucose transporter. It has to move the glucose in but uses the sodium gradient to push it in instead of directly using ATP.Na gradient was made with Na/K ATPase which uses ATP (therefore it is called primary active transporter). In secondary active transport one molecule must have a higher gradient and uses ATP indirectly.
