Gas Exchange All living organisms respire and they need energy to carry out their life processes in order for organisms to survive and produce. The gases involved in cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in the process‚ ATP is made that can then be used for cellular work. Oxygen is needed to be absorbed from the environment and into the organism’s blood so
