Following chemical changes take place during contraction in the anaerobic and aerobic phases in human body. 1. Glycolysis and Oxidative Breakdown: This process involves many separate enzymes and different intermediates. The end products are pyruvic or lactic acid. The first step in the liberation of energy for contraction is the breakdown of glycogen in the muscle fibre. The glycogen reacts [...]

In this article we will discuss about the mechanism of formation of CO2 with the help of suitable diagrams. We have seen that hydration of CO2 occurs in the blood and the mechanism can be represented as CO2 + H2O ↔ H++ HCO3. Further the H+ is buffered by reduced Hb within the RBC and by plasma buffers outside the [...]
