Coupled respiration

Description

Coupled respiration drives oxidative phosphorylation of the diphosphate ADP to the triphosphate ATP, mediated by proton pumps across the inner mitochondrial membrane. Intrinsically uncoupled respiration, in contrast, does not lead to phosphorylation of ADP, despite of protons being pumped across the inner mt-membrane. Coupled respiration, therefore, is the coupled part of respiratory oxygen flux that pumps the fraction of protons across the inner mt-membrane which is utilized by the phosphorylation system to produce ATP from ADP and Pi. In the OXPHOS state, mitochondria are in a partially coupled state, and the corresponding coupled respiration is the free OXPHOS capacity. In the state of ROUTINE respiration, coupled respiration is the free ROUTINE activity.
