|---|---|---|---|
| Unstarved | C starved | N starved | |

a
The assay was performed with two different concentrations of glucose, 50 and 10 mM. The uptake rate was determined five times for each concentration, and means and minimum and maximum values are indicated.
b
Starvation was performed anaerobically.
c
Starvation was performed aerobically.
