Respiration may refer to:
Biology
*
Cellular respiration
Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP. Cellular respiration may be des ...
, the process in which nutrients are converted into useful energy in a cell
**
Anaerobic respiration
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
In aerobic organisms undergoing re ...
, cellular respiration without oxygen
**
Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state
*
Respiration (physiology)
In physiology, respiration is the movement of oxygen from the outside environment to the cells within Tissue (biology), tissues, and the transport, removal of carbon dioxide in the opposite direction that's to the environment.
The physiological d ...
, transporting oxygen and carbon dioxide between cells and the external environment
**
Respiratory system
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies grea ...
, the anatomical system of an organism used for respiration
**
Breathing
Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
All aerobic creatures need oxygen for cellular ...
, passing air in and out through respiratory organs
**
Aquatic respiration
Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.
Unicel ...
, animals extracting oxygen from water
**
Artificial respiration
Artificial ventilation (also called artificial respiration) is a means of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body by pulmonary ventilation, external respiration, and interna ...
, the act of simulating respiration, which provides for the overall exchange of gases in the body by pulmonary ventilation, external respiration and internal respiration
**
Cheyne–Stokes respiration, an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea

Ecology
*
Carbon respiration
Carbon respiration (also called carbon emissions and carbon releases) is used in combination with carbon fixation to gauge carbon flux (as CO2) between atmospheric carbon and the global carbon cycle
Basic process
Carbon is released to the at ...
, a concept used in calculating carbon (as ) flux occurring in the atmosphere
*
Ecosystem respiration
Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem. The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon- ...
, measurement of gross carbon dioxide production by all organisms in an ecosystem
*
Root respiration, exchange of gases between plant roots and the atmosphere
*
Photorespiration
Photorespiration (also known as the oxidative photosynthetic carbon cycle or C2 cycle) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. The desired reaction i ...
, enzymatic combination of RuBP with oxygen
