Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]]. [2] [better source needed] Respiration can be either aerobic, requiring oxygen, or anaerobic; some organisms can switch between aerobic and anaerobic respiration. [3] [better source needed]
When a phagocyte ingests bacteria (or any material), its oxygen consumption increases. The increase in oxygen consumption, called a respiratory burst, produces reactive oxygen-containing molecules that are anti-microbial. [32] The oxygen compounds are toxic to both the invader and the cell itself, so they are kept in compartments inside the cell.
Intracellular bacteria are bacteria that have the capability to enter and survive within the cells of the host organism. [1] These bacteria include many different pathogens that live in the cytoplasm and nuclei of the host cell's they inhabit. Two examples of intracellular pathogenic bacteria are Mycobacterium tuberculosis and also Toxoplasma ...
Lipoarabinomannan is a lipoglycan and major virulence factor in the bacteria genus Mycobacterium. In addition to serving as a major cell wall component, it is thought to serve as a modulin with immunoregulatory and anti-inflammatory effects.
In some bacteria and archaea, ATP synthesis is driven by the movement of sodium ions through the cell membrane, rather than the movement of protons. [ 78 ] [ 79 ] Archaea such as Methanococcus also contain the A 1 A o synthase, a form of the enzyme that contains additional proteins with little similarity in sequence to other bacterial and ...
In cell division, two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by myxobacteria and aerial hyphae formation by Streptomyces species, or budding. Budding ...
It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells. [1] [2] [3] [page needed] If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of ...
In comparison to batch culture, bacteria are maintained in exponential growth phase, and the growth rate of the bacteria is known. Related devices include turbidostats and auxostats . When Escherichia coli is growing very slowly with a doubling time of 16 hours in a chemostat most cells have a single chromosome.
