Fig. 4

Simulated progress curves under the conditions chosen to simulate high-light conditions. The values of the rate constants and initial conditions used are those indicated in Tables 1 and 2, except a _i (min) = 4x10⁶ μM h⁻¹, a _i (max) = 5x10⁶ μM h⁻¹, k ₁₁  = 3.5x10⁴ h⁻¹, k ₁₂  = 500 μM⁻¹ h⁻¹, k ₁₃  = 1,850 μM⁻¹ h⁻¹, k ^APX₅ = 0.1 h⁻¹ and [MDAR]₀ = 0. In abscissa, white bars indicate light, while black denote the dark. Line colors for F _j as indicated for c _j . For greater clarity, c _j have been plotted only for the first day
