Aerobic and anaerobic from normoxia to anoxia: oxygen availability and metabolic state or rate

Oxygen availability: state

Normoxic
Hyperoxic
Hypoxic - "Metabolic hypoxia is indicated as a reduced oxygen flux below the critical oxygen pressure and is either fully or partially anaerobic." [1]
Microxic - "Microxic regulation .. effectively increases the slope of the flux-pressure relation in the microxic region." [1]

Metabolism: state or rate

Aerobic - Whereas anaerobic metabolism may proceed in the absence or presence of oxygen (anoxic or oxic conditions), aerobic metabolism is restricted to oxic conditions.
Anaerobic - "In zoophysiology, 'anaerobic' (without air) is rarely defined in terms of controlled measurements of the actual extent of anaerobic conditions. [1]
Anoxic - "When strictly anoxic conditions are not achieved, anaerobic metabolism proceeds simultaneously with oxygen consumption." [2]

Critical and limiting p_O₂
