title: A relationship between the rates of acetyl group oxidation and the oxygen consumption of cellls.
abstract: A simple relationship has been derived that may be useful in determining the energy production in the tricarboxylic acid cycle in most tissues or whole organisms during fasting or exercise. The ratio of the rate of acetyl group oxidation to the rate of O2 consumption is nearly constant (0.34), irrespective of the proportion of glucose and fatty acids oxidized in a tissue or an organism. This relationship is derived by multiplying the respiratory quotient by the ratio of acetyl group oxidation to total CO2 production.
