Coupling/pathway control diagram
Description
Coupling-pathway control diagrams illustrate the respiratory states obtained step-by-step in substrate-uncoupler-inhibitor titrations in a SUIT protocol. Each step (the next state) is defined by an initial state and a metabolic control variable, X. The respiratory states are shown by boxes. X is usually the titrated substance in a SUIT protocol. If X (such as ADP or an uncoupler) exerts coupling control, then a transition is induced between two coupling control states. If X (such as pyruvate, succinate, or rotenone) exerts pathway control, then a transition is induced between two pathway control states. The type of metabolic control (X) is shown by arrows linking two respiratory states, with vertical arrows indicating coupling control, and horizontal arrows indicating pathway control. Marks in DatLab define the section of an experimental trace in a given respiratory state in the SUIT protocol. Events in DatLab define the titration of X in the SUIT protocol. The specific sequence of coupling control and pathway control steps defines the SUIT protocol pattern. The coupling-pathway control diagrams define the categories of SUIT protocols (see Figure).
