WebTopics and Subtopics in NCERT Solutions for Class 11 Biology Chapter 17 Breathing and Exchange of Gases: Cells continuously use oxygen (O 2) for the catabolic reactions that releases energy from molecules, e.g., breakdown of nutrient molecules like glucose. Thus, O 2 has to be provided to the cells constantly. WebAnswers (1) The oxygen dissociation curve is a graph which shows the percentage of saturation of oxyhaemoglobin at various partial pressures of oxygen. This curve shows the equilibrium of oxyhaemoglobin and haemoglobin at various partial pressures. In the case of the lungs, the partial pressure of oxygen is high.
