The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
Aerobic organisms use a process called aerobic respiration to create ATP from ADP and a phosphate. Glucose (a monosaccharide ) is oxidized to power the electron transport chain: [ 8 ] This equation is a summary of what happens in three series of biochemical reactions: glycolysis , the Krebs cycle (also known as the Citric acid cycle ), and ...
The process of dispersal of aerobiological particles has 3 steps: removal from source, dispersion through air, and deposition to rest. [8] The particle geometry and environment affect all three phases, however once it is aerosolized, its fate depends on the laws of physics governing the motion of the air.
Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration. In most fish , and a number of other aquatic animals (both vertebrates and invertebrates ), the respiratory system consists of gills , which are either partially or completely external organs, bathed in the ...
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 contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
The community of living organisms in conjunction with the nonliving components (e.g., water, light, radiation, temperature, humidity, atmosphere, acidity, and soil) of their environment is called an ecosystem. [147] [148] [149] These biotic and abiotic components are linked together through nutrient cycles and energy flows. [150]
Also called an antibacterial. A type of antimicrobial drug used in the treatment and prevention of bacterial infections. Archaea One of the three recognized domains of organisms, the other two being Bacteria and Eukaryota. artificial selection Also called selective breeding. The process by which humans use animal breeding and plant breeding to selectively control the development of particular ...
best practice - a process, or innovative use of technology, equipment or resources or other measurable factors that have a proven record of success. bioaccumulation - the accumulation of a substance, such as a toxic chemical, in the tissues of a living organism. biocapacity - a measure of the biological productivity of an area. This may depend ...
