Resistance of C. reinhardtii suspended in quenching solution to leakage

Activities refer to 1 mL of cell suspension and for the quench samples to the volume of quench supernatant corresponding to 1 mL of cell suspension. The quenching was performed in triplicates. Mean and se for the measured activities are indicated; percentage values refer to means.
