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. |

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:0008152
|
metabolic process
|
A cellular process consisting of the biochemical pathways by which a living organism transforms chemical substances. This includes including anabolism (biosynthetic process) and catabolism (catabolic process). Metabolic processes includes the transformation of small molecules, as well macromolecular processes such as DNA repair and replication, protein synthesis and degradation. |
|
GO:0009058
|
biosynthetic process
|
A cellular process consisting of the biochemical pathways by which a living organism synthesizes chemical substances. This typically represents the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones. |
|
GO:0042440
|
pigment metabolic process
|
The chemical reactions and pathways involving pigment, any general or particular coloring matter in living organisms, e.g. melanin. |
|
GO:0046148
|
pigment biosynthetic process
|
The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin. |
|
GO:0033013
|
tetrapyrrole metabolic process
|
The chemical reactions and pathways involving tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. |
|
GO:0006778
|
porphyrin-containing compound metabolic process
|
The chemical reactions and pathways involving any member of a large group of derivatives or analogs of porphyrin. Porphyrins consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. |
|
GO:0006779
|
porphyrin-containing compound biosynthetic process
|
The chemical reactions and pathways resulting in the formation of any member of a large group of derivatives or analogs of porphyrin. Porphyrin consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. |
|
GO:0033014
|
tetrapyrrole biosynthetic process
|
The chemical reactions and pathways leading to the formation of tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. |
|
GO:0015994
|
chlorophyll metabolic process
|
The chemical reactions and pathways involving chlorophyll, any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment. |
|
GO:0015995
|
chlorophyll biosynthetic process
|
The chemical reactions and pathways resulting in the formation of chlorophyll, any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment, from less complex precursors. |
|
GO:0030493
|
bacteriochlorophyll metabolic process
|
The chemical reactions and pathways involving a bacteriochlorophyll, any of the chlorophylls of photosynthetic bacteria. They differ structurally from the chlorophylls of higher plants. |
|
GO:0030494
|
bacteriochlorophyll biosynthetic process
|
The chemical reactions and pathways resulting in the formation of a bacteriochlorophyll, any of the chlorophylls of photosynthetic bacteria. They differ structurally from the chlorophylls of higher plants. |
|
GO:0036068
|
light-independent chlorophyll biosynthetic process
|
The chemical reactions and pathways resulting in the formation of chlorophyll, any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment, from less complex precursors, which occur in the absence of light. |
|
GO:0036070
|
light-independent bacteriochlorophyll biosynthetic process
|
The chemical reactions and pathways resulting in the formation of a bacteriochlorophyll, which occur in the absence of light. Bacteriochlorophylls are any of the chlorophylls of photosynthetic bacteria; they differ structurally from the chlorophylls of higher plants. |
