a Mean ± confidence level (p = 0.05). Values in the same rows followed by different letters are significantly different at p < 0.05 by t-test. a, b, c—0.05 > p > 0.005.; d—did not differ significantly. The incubation medium for the experiments contained 50 mM KPi, pH 5.5; and 1% glucose. Values are mean ± S.E.M from 5–6 independent experiments.
