Description
Respiratory states of mitochondrial preparations and intact cells are defined in the current literature in many ways and with a diversity of terms. The Bioblast Wiki aims at providing detailed explanations of terms, improving definitions, and clarification of underlying concepts.

HRR: Theory
Coupling control states
Coupling states and CCR of mitochondrial preparations:
Coupling states of intact cells:
Substrate control states
Control by substrate type: Pathway control states:
- Intact cells: endogenous, exogenous substrate control
- Mitochondrial preparations: specific substrate-inhibitor combinations for selectively stimulating electron entry though Complex I, CII, or other branches converging at the Q-junction, particularly with fatty acids and alpha-glycerophosphate (CI respiration, CII respiration, etc.), or substrate combinations applied for reconstitution of TCA cycle function (CI+II respiration, etc.).
Control by substrate concentration: Kinetic control states:
- Kinetic substrate or adenylate control: Kinetic studies with variation of a specific substrate (reduced substrate supplying electrons to the ETS; ADP, Pi; O2; cytochrome c) are analyzed by kinetic functions (e.g. hyperbolic), yielding apparent kinetic constants, such as Jmax, Km', c50, or p50.
- Kinetic inhibitor control: Kinetic studies with variation of a specific inhibitor yield apparent kinetic constants, such as the KI'.
