Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of oxygen.
Anaerobic respiration generally occurs in lower organisms, such as bacteria and fungi.
The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof and J. Parnas, and is often referred to as the EMP pathway, after the abbreviation of their last names.
Glycolysis is the first stage in the breakdown of glucose and is common to all organisms.
Citric Acid cycle was elucidated by the British biochemist, Hans Krebs, in 1937. The elucidation of this cycle explains how pyruvate is broken down to CO2 and H2O.
The energy released during the electron transport system is utilized in synthesizing ATP with the help of ATP synthase.
The carbon dioxide compensation point is reached when the amount of CO2 uptake is equal to that generated through respiration at a non-limiting light intensity. Net photosynthesis under these conditions is zero.
The ratio of the volume of CO2 evolved to the volume of O2 consumed in respiration is called respiratory quotient (RQ) or respiratory ratio.
