GO:0006810 transport The directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore.
GO:0055085 transmembrane transport The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
GO:0022857 transmembrane transporter activity Enables the transfer of a substance from one side of a membrane to the other.
GO:0005215 transporter activity Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
GO:0015267 channel activity Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules.
GO:0007154 cell communication Any process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment.
GO:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0044763 single-organism cellular process Any process that is carried out at the cellular level, occurring within a single organism.
GO:0044699 single-organism process A biological process that involves only one organism.
GO:0051179 localization Any process in which a cell, a substance, or a cellular entity, such as a protein complex or organelle, is transported to or maintained in a specific location.
GO:1902578 single-organism localization A localization which involves only one organism.
GO:0008150 biological_process Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
GO:0003674 molecular_function Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
GO:0051234 establishment of localization The directed movement of a cell, substance or cellular entity, such as a protein complex or organelle, to a specific location.
GO:0044765 single-organism transport The directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore, involving a single organism.
GO:0065007 biological regulation Any process that modulates a measurable attribute of any biological process, quality or function.
GO:0050789 regulation of biological process Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.
GO:0023052 signaling The entirety of a process in which information is transmitted within a biological system. This process begins with an active signal and ends when a cellular response has been triggered.
GO:0044700 single organism signaling A signaling process occurring within a single organism.
GO:0022803 passive transmembrane transporter activity Enables the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient.
GO:0022829 wide pore channel activity Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts.
GO:0044707 single-multicellular organism process A biological process occurring within a single, multicellular organism.
GO:0032501 multicellular organismal process Any biological process, occurring at the level of a multicellular organism, pertinent to its function.
GO:0051239 regulation of multicellular organismal process Any process that modulates the frequency, rate or extent of a multicellular organismal process, the processes pertinent to the function of a multicellular organism above the cellular level; includes the integrated processes of tissues and organs.
GO:0044057 regulation of system process Any process that modulates the frequency, rate or extent of a system process, a multicellular organismal process carried out by any of the organs or tissues in an organ system.
GO:1903522 regulation of blood circulation Any process that modulates the frequency, rate or extent of blood circulation.
GO:0008016 regulation of heart contraction Any process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process in which the heart decreases in volume in a characteristic way to propel blood through the body.
GO:0005243 gap junction channel activity A wide pore channel activity that enables a direct cytoplasmic connection from one cell to an adjacent cell. The gap junction can pass large solutes as well as electrical signals between cells. Gap junctions consist of two gap junction hemi-channels, or connexons, one contributed by each membrane through which the gap junction passes.
GO:0010644 cell communication by electrical coupling The process that mediates signaling interactions between one cell and another cell by transfer of current between their adjacent cytoplasms via intercellular protein channels.
GO:0035637 multicellular organismal signaling The transfer of information occurring at the level of a multicellular organism.
