A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus reflecting the presence, absence, or concentration of oxygen. The series of events in which an oxygen stimulus is received by a cell and converted into a molecular signal. The series of events in which a stimulus indicating lowered oxygen tension is received by a cell and converted into a molecular signal. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. The series of events in which a chemical stimulus is received by a cell and converted into a molecular signal. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). The process by which information about the levels of oxygen are received and are converted to a molecular signal by chemoreceptors in the carotid bodies and the aortic bodies.
