In general, they use neither. The terms active and passive transport refer to movement ACROSS cell membranes--from one side to the other. Neurotransmitters are packaged inside membrane and they leave the neuron through exocytosis. They re-enter the neuron through receptor-mediated endocytosis. That means they never really pass THROUGH the membrane.
It's passive as the drug is just dumped into the blood stream;
noradrenaline is actively distributed - via nerves.
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
Active transport requires energy; passive transport does not.
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)
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
Passive Transport, and if your dealing with liquids its is Osmosis. Passive Transport is the act of transport with no use of energy: hence the word "Passive." But Active Transport is when it does use energy: hence the word "Active."

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.
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.

Passive Transport
there is no requirement of energy for this motion so it is a passive process
