The efficiency of cellular respiration is about _____ of the energy in one glucoe molecule. The rest of the potential energy from glucose is dissipated as _____ energy.
The efficiency of cellular respiration is about 41% of the energy in one glucoe molecule. The rest of the potential energy from glucose is dissipated as thermal energy.
