The series of events in which a stimulus is received by a cell or organism 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 stimulus reflecting the presence, absence, or concentration of oxygen. 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 an oxygen stimulus is received by a cell and converted into a molecular signal. 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 chemical stimulus.
