Figure 5. Photorespiratory level in Synechococcus 7942 cells at changing CO2 levels.

Figure 5

PGPase–2-phosphoglycolate phosphatase, pPGPase–putative PGPase. Photorespiratory level– the percentage of RuBisCO capacity used by its oxygenase activity. Figure represents two scenarios of the same high → low CO2 transition. Two steady states and one transient state are shown.
