no. only endocytosis, exocytosis and substance trafficking
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
the sodium potassium pump.
Active transport
sodium-potassium pump.
Na+/K+ ATPase active transport pump
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
antiport: transports 2 solutes in opposite directions (example: Na/K pump)
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Yes, certainly enzymes are involved and energy is expended.

Active transport is the type of transport where a cell must expend energy. These are endocytosis, exocytosis, and the sodium-potassium pump.
Solute pump
active transport pump
In the tank
Active Transport is when the cell uses energy to pump a solute across the membrane against a concentration gradient (the place where the density of a substance decreases). Passive Transport, on the other hand, does not require the cell to use energy to move things in and out of the membrane because of diffusion (where molecules move until everything is spread out evenly).Think of it like barrels on a hill. You're actively using energy to push the barrel up the hill (when the cell pumps the solute against the concentration gradient) but no energy is used when you passively let it roll down (the solute rolls away from where everything is concentrated by diffusion until both sides of the membrane are equal to each other).Active transport requires energy.
