The development and control of coexisting respiratory systems in slices of chicory root

摘要: Abstract 1. The respiratory rise which occurs in incubated thin slices of chicory root may be controlled by a variety environmental factors. By regulating either the lithium- or bicarbonate-ion concentration incubation medium, controlling CO2 O2 tension gas phase, prevented, its nature altered. 2. Whereas increment normally arises on is completely malonate sensitive, it predominantly resistant when carried out solutions selected concentrations lithium bicarbonate, at high partial pressures CO2, low oxygen tensions. 3. Under conditions where an increase respiration can occur, malonate-resistant rises proportion to extent development (as distinct from activity) malonate-sensitive repressed. 4. arising upon under apparently different basal respiration. It suggested that preempts latter but not former. 5. Whenever some fraction total malate restores rate malonate-treated tissue. 6. A suggestion offered for means whereby disparate factors exert common influence.
