when a glucose molecule is converted to carbon dioxide and water during cellular respiration, energy is released and stored in potential energy atp molecules. the three phases of cel- lular respiration that oxidize the glucose molecule to carbon dioxide are glycolysis, the link reaction and the krebs cycle.
we get increasing returns in the first stage because initially, the fixed factors are abundant relative to the variable factor. the introduction of additional units of the variable factor leads to the effective utilisation of the fixed factors. evidently, production increases at an increasing rate.
