Enthalpy conservation efficiency

Calculation of enthalpy conservation efficiencies for aerobic growth processes. 

The same methods used above in Section 3.5.2. for calculating free energy conservation efficiencies can be used to calculate enthalpy conservation efficiencies. Using appropriate data from Table 3, the enthalpy change Af-l f accompanying the process represented by equation (25) is calculated to be -463.89 kJ ICCmol. For the growth of 5. cerevisiae aerobically on glucose as represented in Table 2 ... 

Values for the fi ee energy and enthalpy conservation efficiency during anaerobic growth can also be calculated using the same methods as for aerobic growth. To calculate free energy conservation efficiencies... 

Calculating enthalpy conservation efficiencies for anaerobic growth processes. 

The sum of the efficiency values above represents the total enthalpy conservation efficiency. The fraction of the enthalpy that is lost during metabolism must then be (1 - 0.964). From this... 

The quantum efficiency for solid-state devices, e.g. solar cells, is always below unity. For n-type silicon electrodes anodized in aqueous or non-aqueous HF electrolytes, quantum efficiencies above unity are observed because one or more electrons are injected into the electrode when a photogenerated hole enters the electrolyte. Note that energy conservation is not violated, due to the enthalpy of the electrochemical dissolution reaction of the electrode. 

To analyze the influence of transfer phenomena on the energy efficiency of plasma-chemical processes, consider conservation eqrratiorrs, describing enthalpy (7) and mass transfer in...
