WebThe process of gas exchange The gases are transferred between the organism’s internal and external environments. The transfer occurs passively (no energy required), down the concentration gradient. The transfer of gases includes the exchange of oxygen and carbon dioxide during the respiration and photosynthesis processes. WebThree Important Things. 1. The absorption coefficient (A) is a measure of gas solubility. The higher the A, the more readily a gas will dissolve (at any partial pressure). The A of CO 2 is much higher than the A of O 2 . Thus, CO 2 dissolves in water more readily than O 2 under the same conditions. 2. imperfect foods leadership
