Basal respiration
Description
Basal respiration or 'basal metabolic rate' (BMR) is the minimal rate of metabolism required to support basic body functions or required for maintenance only, measured at rest 12 to 14 hours after eating. The term metabolic 'rate' is frequently used for metabolic flux (oxygen flux). Metabolic flux is a system size-specific quantity expressed per kg body weight or per surface area of the body. Maintenance energy requirements include particularly the metabolic costs of ion homeostasis and protein turnover.

Respiratory states: from physiology to mitochondrial respiration
- Standard respiration refers to oxygen consumption measured with minimal motor activity, frequently made on anesthetized animals (Prosser CL, Brown FA 1961. Comparative Animal Physiology. Saunders).
- Routine respiration is usually higher than standard or basal respiration due to the oxygen consumption required to sustain various routine activities, not restricted to locomotory activity, but including the effects of food or substrate availability, growth conditions. In intact cells, ROUTINE respiration varies as a function of cell cycle and substrate supply.
- LEAK respiration is the energy expenditure required mainly to compensate for the proton leak through the inner mitochondrial membrane, but additionally including energy expenditure caused by proton slip and cation cycling through the inner mitochondrial membrane in general.
