Isopoda is an order of crustaceans.Members of this group are called isopods and include both aquatic species and terrestrial species such as woodlice.All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration.
In very small animals, plants and bacteria, simple diffusion of gaseous metabolites is sufficient for respiratory function and no special adaptations are found to aid respiration. Passive diffusion or active transport are also sufficient mechanisms for many larger aquatic animals such as many worms, jellyfish, sponges, bryozoans and similar ...
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 ...
Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...
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 ...
Lungfish are freshwater vertebrates belonging to the class Dipnoi. [1] Lungfish are best known for retaining ancestral characteristics within the Osteichthyes, including the ability to breathe air, and ancestral structures within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton.
Mice are the most commonly used mammal species for live animal research. Such research is sometimes described as vivisection. Vivisection (from Latin vivus 'alive' and sectio 'cutting') is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure.
Some obligate anaerobes use fermentation, while others use anaerobic respiration. [12] Aerotolerant organisms are strictly fermentative. [13] In the presence of oxygen, facultative anaerobes use aerobic respiration. [7] In the absence of oxygen, some facultative anaerobes use fermentation, while others may use anaerobic respiration.
