  2. Triosephosphate isomerase - Wikipedia

    en.wikipedia.org/wiki/Triosephosphate_isomerase

    TPI is diffusion-limited. In terms of thermodynamics, DHAP formation is favored 20:1 over GAP production. [8] However, in glycolysis, the use of GAP in the subsequent steps of metabolism drives the reaction toward its production. TPI is inhibited by sulfate, phosphate, and arsenate ions, which bind to the active site. [9]

  3. Rapids - Wikipedia

    en.wikipedia.org/wiki/Rapids

    Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Flow, gradient, constriction, and obstacles are four factors that are needed for a rapid to be created.

  5. Operational taxonomic unit - Wikipedia

    en.wikipedia.org/wiki/Operational_taxonomic_unit

    An operational taxonomic unit (OTU) is an operational definition used to classify groups of closely related individuals.The term was originally introduced in 1963 by Robert R. Sokal and Peter H. A. Sneath in the context of numerical taxonomy, where an "operational taxonomic unit" is simply the group of organisms currently being studied. [1]

  6. Order (biology) - Wikipedia

    en.wikipedia.org/wiki/Order_(biology)

    It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of ...

  7. Taxonomic rank - Wikipedia

    en.wikipedia.org/wiki/Taxonomic_rank

    In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary

  8. Liebig's law of the minimum - Wikipedia

    en.wikipedia.org/wiki/Liebig's_law_of_the_minimum

    Liebig's law has been extended to biological populations (and is commonly used in ecosystem modelling).For example, the growth of an organism such as a plant may be dependent on a number of different factors, such as sunlight or mineral nutrients (e.g., nitrate or phosphate).

  9. Domain (biology) - Wikipedia

    en.wikipedia.org/wiki/Domain_(biology)

    [1] According to the domain system, the tree of life consists of either three domains, Archaea, Bacteria, and Eukarya, [1] or two domains, Archaea and Bacteria, with Eukarya included in Archaea. [3] [4] In the three-domain model, the first two are prokaryotes, single-celled microorganisms without a membrane-bound nucleus.
