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 transfer chemical ...
[1] [2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1] Aerobic respiration has the advantage of yielding more energy (adenosine triphosphate or ATP) than fermentation or anaerobic respiration, [3] but obligate aerobes are subject to high levels of oxidative stress. [2]
In fish a countercurrent flow (lower diagram) of blood and water in the gills is used to extract oxygen from the environment. [56] [57] [58] Fig. 23 The respiratory mechanism in bony fish. The inhalatory process is on the left, the exhalatory process on the right. The movement of water is indicated by the blue arrows. Oxygen is poorly soluble ...
The end products of an aerobic process are primarily carbon dioxide and water which are the stable, oxidised forms of carbon and hydrogen. If the biodegradable starting material contains nitrogen , phosphorus and sulfur , then the end products may also include their oxidised forms- nitrate , phosphate and sulfate . [ 1 ]
An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. [1] The ability to exhibit aerobic respiration may yield benefits to the aerobic organism, as aerobic respiration yields more energy than anaerobic respiration. [2] Energy production of the cell involves the synthesis of ATP by an enzyme called ...
Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem. [1] The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon-dioxide and water, in the presence of sunlight to produce glucose and oxygen whereas cellular ...
The rate of change gives a direct and reasonably accurate reading for the organism's rate of respiration. As changes in temperature or pressure can also affect the displacement of the manometric fluid, a second respirometer identical to the first except with a dead specimen (or something with the same mass as the specimen in place of the ...
The overall process of cellular respiration can be summarized with, C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + ATP. The ATP created during cellular respiration is absolutely necessary for a living being to function as it is the 'Energy currency" of the cell [ 5 ] and none of the other metabolic functions could be sustained without it.
