The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
ATP is used for all the processes inside the body that require energy, such as muscle movement, and active transport.

Active transport is when energy is spent to moving a nutrient from Point A to Point B. It is the opposite of Diffusion.
diffusion occurs naturally facilitated diffusion and active transport need energy

Passive transport
The mechanism of pulmonary respiration: It includes breathing movement, exchange of gases, in lungs, transport of gases by blood and exchange of gase by tissue.
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
There are three types of cellular movement. These are active transport, diffusion, and osmosis. All are very important in growth and movement.

Diffusion and osmosis ( movement of molecules from higher concentration to lower concentration until evenly spread.)
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
ATP is used for all the processes inside the body that require energy, such as muscle movement, and active transport.
the direction of movement of oxygen from the air you breathe and to dispose of excess.
