| GO:0007165 | signal transduction | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. |
| GO:0004871 | signal transducer activity | Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. |
| GO:0009416 | response to light 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 light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light. |
| GO:0009585 | red, far-red light phototransduction | The sequence of reactions within a cell required to convert absorbed photons from red or far-red light into a molecular signal; the red, far-red light range is defined as having a wavelength within the range 660-730 nm. |
| GO:0009881 | photoreceptor activity | The function of absorbing and responding to incidental electromagnetic radiation, particularly visible light. The response may involve a change in conformation. |
| GO:0004872 | receptor activity | Combining with an extracellular or intracellular messenger to initiate a change in cell activity. |
| GO:0051716 | cellular response to stimulus | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus by a cell and ends with a change in state or activity or the cell. |
| 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:0009639 | response to red or far red light | 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 red or far red light stimulus. Red light is electromagnetic radiation of wavelength of 580-700nm. Far red light is electromagnetic radiation of wavelength 700-800nm. An example of this response is seen at the beginning of many plant species developmental stages. These include germination, and the point when cotyledon expansion is triggered. In certain species these processes take place in response to absorption of red light by the pigment molecule phytochrome, but the signal can be reversed by exposure to far red light. During the initial phase the phytochrome molecule is only present in the red light absorbing form, but on absorption of red light it changes to a far red light absorbing form, triggering progress through development. An immediate short period of exposure to far red light entirely returns the pigment to its initial state and prevents triggering of the developmental process. A thirty minute break between red and subsequent far red light exposure renders the red light effect irreversible, and development then occurs regardless of whether far red light exposure subsequently occurs. |
| 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: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: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:0065007 | biological regulation | Any process that modulates a measurable attribute of any biological process, quality or function. |
| GO:0050794 | regulation of cellular process | Any process that modulates the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. |
| 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:0038023 | signaling receptor activity | Receiving a signal and transmitting the signal 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: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:0060089 | molecular transducer activity | The molecular function that accepts an input of one form and creates an output of a different form. |
| GO:0009628 | response to abiotic 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 an abiotic (non-living) stimulus. |
| GO:0071214 | cellular response to abiotic stimulus | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an abiotic (non-living) stimulus. |
| GO:0009605 | response to external 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 an external stimulus. |
| 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:0009581 | detection of external stimulus | The series of events in which an external stimulus is received by a cell and converted into a molecular signal. |
| GO:0009582 | detection of abiotic stimulus | The series of events in which an (non-living) abiotic stimulus is received by a cell and converted into a molecular signal. |
