Passive Transports
active transports
active transport requires input of energy as it takes place aginst a gradient.
active transportactive transportExocytosis & endocytosis are types of active transport, because they expend energy in order to transfer things into and out of a cell.
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
Active transport is when the cell moves particles from an area of low concentration on one side of the cell membrane, to an area of high conc. on the other side, by means of a protein embedded in the membrane.

Yes, require to spend energy
It doesn't require the cell to expend energy.

No. Endocytosis requires the cell to expend energy, therefore it is a form of active transport.
Generally, cells derive their energy from ATP (in their phosphate bond).
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
Active transport is the type of transport where a cell must expend energy. These are endocytosis, exocytosis, and the sodium-potassium pump.
Yes, facilitated diffusion is an example of passive transport. The cell does not expend any energy; integral proteins in the cell's surface membrane act as carriers.
