Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and

Oxygen Exchange and Transport Oxygen exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) move in opposite directions across an organism’s respiratory membranes‚ between the air or water of the external environment and the body fluids of the internal environment. Oxygen is needed by cells to extract energy from organic molecules
