ROUTINE respiration

Description

In the intact cell, ROUTINE respiration in the physiological coupling state R, is controlled by cellular energy demand, energy turnover and the degree of coupling to phosphorylation (intrinsic uncoupling and pathological dyscoupling). R and growth of cells is supported by exogenous substrates in culture media. In media without energy substrates, R depends on endogenous substrates. R cannot be measured in permeabilized cells or isolated mitochondria.

Abbreviation: R

Why not 'basal respiration', and what about 'State 3.5'?

Basal respiration or "basal metabolic rate" is frequently used in the context of isolated mitochondria as LEAK respiration (State 4). Importantly, we have to make a clear distinction between (oligomycin-inhibited) LEAK respiration and physiologically controlled ROUTINE respiration, none of which conform to the physiological definition of basal respiration.
