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: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: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: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:0050958
|
magnetoreception
|
The series of events required for an organism to receive a stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. Stimuli may be chemical, mechanical or electrical and interpreting these stimuli allows an organism to determine the orientation of a magnetic field. Magnetoreception also involves the perception of light; birds cannot orient without the presence of short wavelength (blue/green) light. |
|
GO:0050969
|
detection of chemical stimulus involved in magnetoreception
|
The series of events involved in magnetoception in which a chemical stimulus is received and converted into a molecular signal. It is believed that organisms such as birds and salamanders interpret product ratios in chemical reactions which involve transitions between different spin states. |
|
GO:0050977
|
magnetoreception by sensory perception of chemical stimulus
|
The series of events required for an organism to receive a chemical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. It is believed that organisms such as birds and salamanders use a 'chemical compass': chemical reactions that involve transitions between different spin states can be influenced by magnetic fields and by detecting the different product ratios, these organisms can perceive the direction of the magnetic field. The mechanism by which this is detected is not certain but it may also involve light stimuli. |
