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.

active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
Energy, versus passive in which energy is not used.
ATP is often used as the source of energy during active transport.
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.

Yes, that's correct. The sodium-potassium pump actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients using energy from ATP. This process helps to maintain the cell's resting membrane potential and is essential for cellular function.
The energy used in active transport is derived from ATP (adenosine triphosphate), which is produced through cellular respiration in the mitochondria of cells. ATP provides the necessary energy for the transport proteins to move molecules against their concentration gradient across the cell membrane.

ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.

Adenosine triphosphate (ATP) is the molecule that supplies the energy for active transport in cells. ATP is produced during cellular respiration and carries energy that is used by transport proteins to move molecules against their concentration gradient.
Adenosine triphosphate (ATP) is the primary molecule used in active transport processes to provide energy for moving molecules against their concentration gradient. ATP is hydrolyzed to ADP + Pi (inorganic phosphate) to release energy that drives the transport of ions or molecules across a membrane.
