Respiration may refer to:
Biology
*
Cellular respiration
Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which stores chemical energy in a biologically accessible form. Cell ...
, 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 ...
, 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 transport of oxygen from the outside environment to the Cell (biology), cells within Tissue (biology), tissues, and the removal of carbon dioxide in the opposite direction to the environment by a respiratory syste ...
, 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 (spiration or ventilation) is the rhythmical process of moving air into ( inhalation) and out of ( exhalation) the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxy ...
, passing air in and out through respiratory organs
**
Aquatic respiration
Aquatic respiration is the Biological process, process whereby an aquatic animal, aquatic organism exchanges Respiration (physiology), respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excretion, excreting carbon ...
, animals extracting oxygen from water
**
Artificial respiration
Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. A machine called a ventilator provides the person air ...
, 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

Karger Publishers
Ecology
*
Carbon respiration
Carbon respiration (also referred to as carbon emissions and carbon releases) is the global release into the atmosphere of carbon through natural and artificial processes. It is used in combination with carbon fixation to gauge carbon flux (inclu ...
, a concept used in calculating carbon (as ) flux occurring in the atmosphere
*
Ecosystem respiration, 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 physiology, plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. Th ...
, enzymatic combination of RuBP with oxygen
