Passive transport... the opposite of active transport.
passive transport
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
active transport reguire energy.

electron transport chain
There are several unique cell processes that require energy. Anabolism is the energy requiring process the cell performs to order to synthesize cellular building blocks and grow.
No, diffusion is passive transport.Active transport would be when there are actual proteins and structures involved in the transportation of molecules/chemicals/etc..A sure sign is that all of these (that I know of) require ATP.An example would be the Sodium-Potassium Pump located along one's neurons which actively pumps (aka. transports) sodium and potassium back and forth across the membrane to build up potential charge. This is how "signals" are sent down neurons and around the body.
Cellular Respiration
Diffusion is per definition a passive transport process.
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
