Lactate production analysis: (a) specific glucose consumption rate versus specific lactate production rate for all experiments; (b) lactate yield coefficient from glucose versus residual glucose concentration for all experiments. Solid line is the Michaelis-Menten fit; (c) lactate yield coefficient from glucose vs. residual glutamine concentration for experiments with 11.5 and 21.0 mM initial glucose concentrations. Solid line is the Michaelis-Menten fit
