O₂ Uptake attributed to FLV proteins. (A) O₂ uptake rate of C6 cells exposed to different light intensities (represented in different colors and indicated on the graph) are plotted during the first 2 min of the light period (300 to 420 s). The rates of baseline O₂ uptake (uptake in the light after the CBBC becomes active), calculated from the data in SI Appendix, Fig. S3, are shown as dashed lines in the color that corresponds to the measurements of total O₂ uptake. (B) Total O₂ uptake at each intensity that cannot be attributed to the basal rate of uptake was calculated by integrating the area under the curves at the different intensities (with baseline set by the rate of basal uptake at that intensity). (C) Rates of O₂ uptake attributed to the FLV proteins at the different light intensities. These values were calculated by subtracting the rate of O₂ uptake attributed to basal uptake from Umax depicted in the curve in A. For all panels n = 3 ± SE.
