The following points highlight the top five processes for diffusion of gases in the lungs. 1. When the gases of the inspired air come in contact with the alveolar membrane of the lung, the exchange of gases takes place following the usual laws of diffusion. Thus, the gas passes into the blood through the membrane. 2. The gas pressure in [...]
In this article we will discuss about the Transport of Oxygen and Carbon Dioxide in the Blood:- 1. Function of Hemoglobin 2. Dissociation of Oxy-hemoglobin 3. Clinical Signs of Variation in Hemoglobin Saturation 4. Transport of CO2 in Blood 5. Effect of CO2 on Blood pH.

In this article we will discuss about the synthesis of ATP formation. In the early 1930s it was clear that the ADP phosphorylation was coupled to respiration. Lehninger and other workers between 1948-51 conducted biochemical studies on isolated mitochondria and tissue samples. From their studies following general inferences emerged: i. Phosphorylation depended upon oxygen. ii. Mitochondria when isolated catalyzed oxygen-dependent [...]
