Figure 5.

The relative contribution of abolishing the energy cost for ammonia refixation (white bars) and relocating photorespiratory CO₂ release into chloroplasts (black bars) on the change in the rate of photosynthesis in bypass under different light intensities and CO₂ partial pressures when all the flux goes through the bypass. For high light (A), PAR = 1,000 μmol m⁻² s⁻¹; for low light (B), PAR = 200 μmol m⁻² s⁻¹.
