Ratios of nicotinamide dinucleotides and of ADP/ATP. All assays were performed as described in Materials and Methods. The assays were run in quadruplicates in 96-well-plates containing the equivalent of 10⁴ cells per well. The mean values and standard errors of three independent assays normalized by the protein contents of the cells are shown. Values marked by asterisks are significantly different to the control (paired t-test, two-sided; *, p < 0.01).

Ratio	WT	C4
ADP/ATP	1.04 ± 0.03	1.4 ± 0.1*
NAD/NADH	32.3 ± 6.3	12.6 ± 2.0
NADPH/NADP	1.31 ± 0.03	1.77 ± 0.02*
