Key model predictions related to the regulation of the electron transport system. These simulations examine the effects of variation in assumptions about how electron transport is coordinated with carbon metabolism: via feedback regulation of Cyt ${\text{b}}_6\text{f}$ alone (Case 5), via feedback regulation of NPQ alone (Case 6), via feedback regulation of NPQ and Cyt ${\text{b}}_6\text{f}$ together (Case 7), and via feedback regulation of NPQ and CEF1 together (Case 8). Results are plotted for the potential and actual rates of LEF and CEF1, the rate constant for NPQ, the fraction of open reaction centers for PS II and PS I, and the rate constant for Cyt ${\text{b}}_6\text{f}$. The input parameters are given in Table 2, and other details are as described in ‘Regulation of electron transport (Cases 5–8)’
