Which one is true about gas exchange? Determining partial pressures enables us to hinder and stop the net movement of a gas at an exchange surface We breathe in carbon dioxide and breathe out oxygen. A gas always undergoes net diffusion from a region of higher partial pressure to a region of lower partial pressure. Partial pressure is pressure exerted by all gas present in a mixture of gases
