82Opsin — Three dimensional structure of bovine rhodopsin. The seven transmembrane domains are shown in varying colors. The chromophore is shown in red. Opsins are a group of light sensitive 35–55 kDa membrane bound G protein coupled receptors of the… …

85Electrochemical gradient — An electrochemical gradient is a spatial variation of both electrical potential and chemical concentration across a membrane; that is, a combination of the membrane potential (delta psi) and the pH gradient (delta pH). Both components are often… …
86Oligotroph — An oligotroph is an organism that can live in an environment that offers very low levels of nutrients. They may be contrasted with copiotrophs, which prefer nutritionally rich environments. Oligotrophs are characterized by slow growth, low rates… …
87Lithotroph — A lithotroph is an organism that uses an inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation via aerobic or anaerobic respiration.[1] Known… …
88Halo- — is a Greek prefix meaning salt. In biology, it is often used to indicate halotolerance and it a portion of many words: *Halobacteria *Halophile *Halophyte …
89Lithoautotroph — A lithoautotroph is a microbe which derives energy from reduced compounds of mineral origin. They may also be referred to as chemolithoautotrophs, a type of lithotrophs, reflecting their autotrophic metabolic pathways. Lithoautotrophs are… …
90Haloarchaea — are microrganisms member of the halophile community, in that they require high salt concentrations to grow. They are a distinct evolutionary branch of the Archaea, and are generally considered extremophiles, although not all members of this group …
