Figure 4
Model interaction structure of the fluorescence induction model for D. salina . Black arrows indicate the forward reactions, while white (not filled) arrows denote backward reactions. F is the dissipated chlorophyll fluorescence, u is the intensity of the excitation light. A denotes the unexcited antennae, A ∗ is the number of excited antennae. Q A and Q B are the first and the second quinone receptors respectively and \(Q_{A}^{-}\), \(Q_{B}^{-}\) and \(Q_{B}^{2-}\) represent their oxidized states. PQ is the plastoquinon pool and P Q H 2 represents its protonated form.
