“On cooling from 45 degrees …, in the presence of pentobarbital (…, glucose ) decreases from 30.6+/-7.8 mM to 14+/-1.9 mM; whereas in control cells, Ki (sorbose, glucose) ….3 mM at 45 degrees C to 23.4+/-4.5 mM at 30 degrees C (P<0.002).”
“ Pentobarbital (8 mM) increases the activation energy of glucose exit from control 54.7+/-2.5 kJ/mol to 114+/-13 kJ/mol (P<0.01).”
“ Pentobarbital acts as a mixed inhibitor of net D-glucose exit, as monitored photometrically from human red cells.”
“ Pentobarbital reduces the temperature coefficient of D-glucose binding to the external site.”
