WebThe sigmoidal pattern of oxygen haemoglobin dissociation curve is the result of two properties which play significant role in the transport of oxygen. These two properties are: (i) Minimal loss of oxygen from haemoglobin occurs above p02 of 70-80 mm Hg despite significant changes in tension of oxygen beyond this. WebOxygen dissociation curve is the sigmoid curve obtained when the percentage saturation of haemoglobin with O 2 is plotted against the partial pressure of oxygen p O 2. It helps in the study of the effect of factors like pC O 2, H + concentration etc. on binding of oxygen with haemoglobin. The binding of oxygen to haemoglobin is in such a way that the …

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. WebAug 7, 2024 · The chapter Breathing and Exchange of Gases explain that O2 and CO2 transportation occurs via the blood. While the blood transports 97% of O2, the remaining 3% is transported through plasma in a dissolved state. Mentioned below are some of the important points related to the transport of gases-.
