|
active transport
|
the transport of solute molecules across a membrane against an electrochemical gradient; it requires a carrier protein and the input of energy
|
|
|
agar
|
a complex sulfated polysaccharide, usually from red algae that is used as a solidifying agent in the preparation of culture media
|
|
|
autotroph
|
an organism that uses CO2 as its sole or principal source of carbon
|
|
|
chemolithoautotroph
|
oxidizes reduced inorganic compounds to derive both energy and electrons; CO2 is the carbon source
|
|
|
chemilithoheterotroph
|
uses reduced inorganic compounds to derive both energy and electrons; ORGANIC MOLECULES used as the carbon source
|
|
|
chemorganoheterotroph
|
uses ORGANIC COMPOUNDS as sources of energy, electrons, carbon
|
|
|
chemotroph
|
uses chemicals ORGANIC or INORGANIC as its source of energy
|
|
|
colony
|
an assemblage of microorganisms growing on a solid surface
|
|
|
facilitated diffusion
|
diffusion across a plasma membrane that is aided by a carrier protein
|
|
|
group translocation
|
a transport process in which a molecule is moved across a membrane by carrier proteins while being chemically altered at the same time (PHOSPHOENOLPYRUVATE; SUGAR PHOSPHOTRANSFERASE SYSTEM).
|
|
|
heterotroph
|
uses reduced, preformed organic molecules as its principal carbon source
|
|
|
lithotroph
|
uses reduced inorganic compounds as its electron source
|
|
|
macroelements/macronutrients
|
Carbon, Hydrogen, Oxygen, Nitrogen, that are required in relatively large amounts; also called macronutrients
|
|
|
micronutrients
|
required in very small amounts - trace elementsL Manganese, Zinc and Copper
|
|
|
organotroph
|
uses reduced organic compounds as its electron source
|
|
|
permease
|
a membrane-bound carrier protein or a system of two or more proteins that transports a substance across a plasma membrane
|
|
|
photoautotroph
|
an organism that uses LIGHT for ENERGY and CO2 as its CARBON SOURCE
|
|
|
photolithoautotroph
|
LIGHT FOR ENERGY, and INORGANIC ELECTRON SOURCE (H2O,H2,H2S) and CO2 as CARBON SOURCE
|
|
|
photoorganoheterotroph
|
LIGHT FOR ENERGY, ORGANIC ELECTRON SOURCES, and ORGANIC MOLECULES as carbon source
|
|
|
phototroph
|
uses light as its source of energy
