biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |
|
GO:0003674
|
molecular_function
|
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. |
|
GO:0050896
|
response to stimulus
|
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism. |
|
GO:0060089
|
molecular transducer activity
|
A compound molecular function in which an effector function is controlled by one or more regulatory components. |
|
GO:0042221
|
response to chemical
|
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a chemical stimulus. |
|
GO:0032501
|
multicellular organismal process
|
Any biological process, occurring at the level of a multicellular organism, pertinent to its function. |
|
GO:0038023
|
signaling receptor activity
|
Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. |
|
GO:0004888
|
transmembrane signaling receptor activity
|
Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity or state as part of signal transduction. |
|
GO:0051606
|
detection of stimulus
|
The series of events in which a stimulus is received by a cell or organism and converted into a molecular signal. |
|
GO:0009593
|
detection of chemical stimulus
|
The series of events in which a chemical stimulus is received by a cell and converted into a molecular signal. |
|
GO:0050906
|
detection of stimulus involved in sensory perception
|
The series of events involved in sensory perception in which a sensory stimulus is received and converted into a molecular signal. |
|
GO:0050907
|
detection of chemical stimulus involved in sensory perception
|
The series of events in which a chemical stimulus is received and converted into a molecular signal as part of sensory perception. |
|
GO:0007600
|
sensory perception
|
The series of events required for an organism to receive a sensory stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. |
|
GO:0050877
|
nervous system process
|
An organ system process carried out by any of the organs or tissues of the neurological system. |
|
GO:0003008
|
system process
|
A multicellular organismal process carried out by any of the organs or tissues in an organ system. An organ system is a regularly interacting or interdependent group of organs or tissues that work together to carry out a biological objective. |
|
GO:0007606
|
sensory perception of chemical stimulus
|
The series of events required for an organism to receive a sensory chemical stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. |
|
GO:0004984
|
olfactory receptor activity
|
Combining with an odorant and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity in response to detection of smell. |
|
GO:0050911
|
detection of chemical stimulus involved in sensory perception of smell
|
The series of events involved in the perception of smell in which an olfactory chemical stimulus is received and converted into a molecular signal. |
|
GO:0007608
|
sensory perception of smell
|
The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological process. |
