| Method |
“From marker enzyme activities and metabolite
contents in the unfractionated homogenate and in
the different fractions the mitochondrial and cytosolic
metabolite contents (nmol/mg protein) were calculated
by extrapolating the data to fractions of pure mitochondria
and pure cytosol according to Elbers et al.
[ref 5]. The subcellular metabolite contents were converted
into concentrations assuming a water content of 0.8 and 3.8 µl/mg protein in the mitochondrial and
cytosolic compartment, respectively, based on considerations
previously discussed by Soboll et al. [ref 1].” |
| Comments |
"Despite the predominance of mitochondrial ATP generation, the liver has also a high capacity to generate ATP in the cytosol. In substrate-free perfused livers from fed rats, the production of lactate + pyruvate was around 100µmol/g/h (Table 2, expt F) yielding 150µmol ATP/g/h due to glycolysis from glycogen, i.e. one fourth of the ATP generated by oxidative phosphorylation."
