| Identifier | Name | Description |
|---|---|---|
| GO:0008152 | metabolic process | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| GO:0044237 | cellular metabolic process | The chemical reactions and pathways by which individual cells transform chemical substances. |
| GO:0005576 | extracellular region | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. |
| GO:0006807 | nitrogen compound metabolic process | The chemical reactions and pathways involving organic or inorganic compounds that contain nitrogen, including (but not limited to) nitrogen fixation, nitrification, denitrification, assimilatory/dissimilatory nitrate reduction and the interconversion of nitrogenous organic matter and ammonium. |
| GO:0071704 | organic substance metabolic process | The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon. |
| GO:0001505 | regulation of neurotransmitter levels | Any process that modulates levels of neurotransmitter. |
| 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: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:0044710 | single-organism metabolic process | A metabolic process - chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances - which involves a single organism. |
| GO:0005575 | cellular_component | The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| GO:0065007 | biological regulation | Any process that modulates a measurable attribute of any biological process, quality or function. |
| GO:0044248 | cellular catabolic process | The chemical reactions and pathways resulting in the breakdown of substances, carried out by individual cells. |
| GO:0044712 | single-organism catabolic process | A catabolic process - chemical reactions and pathways resulting in the breakdown of substances - which involves a single organism. |
| GO:1901575 | organic substance catabolic process | The chemical reactions and pathways resulting in the breakdown of an organic substance, any molecular entity containing carbon. |
| GO:0009056 | catabolic process | The chemical reactions and pathways resulting in the breakdown of substances, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism. |
| 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:0065008 | regulation of biological quality | Any process that modulates a qualitative or quantitative trait of a biological quality. A biological quality is a measurable attribute of an organism or part of an organism, such as size, mass, shape, color, etc. |
| GO:0006581 | acetylcholine catabolic process | The chemical reactions and pathways resulting in the breakdown of acetylcholine, the acetic acid ester of the organic base choline. |
| GO:0001507 | acetylcholine catabolic process in synaptic cleft | The chemical reactions and pathways resulting in the breakdown of acetylcholine that occurs in the synaptic cleft during synaptic transmission. |
| GO:0007271 | synaptic transmission, cholinergic | The process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse using the neurotransmitter acetylcholine. |
| GO:0043083 | synaptic cleft | The narrow gap that separates the presynaptic and postsynaptic membranes, into which neurotransmitter is released. |
| GO:0097164 | ammonium ion metabolic process | The chemical reactions and pathways involving the ammonium ion. |
| GO:0042133 | neurotransmitter metabolic process | The chemical reactions and pathways involving neurotransmitters, any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. |
| GO:0042135 | neurotransmitter catabolic process | The chemical reactions and pathways resulting in the breakdown of any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. |
| GO:0008291 | acetylcholine metabolic process | The chemical reactions and pathways involving acetylcholine, the acetic acid ester of the organic base choline. Acetylcholine is a major neurotransmitter and neuromodulator both in the central and peripheral nervous systems. It also acts as a paracrine signal in various non-neural tissues. |
| GO:0045202 | synapse | The junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell; the site of interneuronal communication. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
