GO Term : GO:0009760 C4 photosynthesis GO

Namespace:  biological_process Obsolete:  false
description  The combination of atmospheric CO2 with a 3-carbon molecule phosphoenol pyruvate (PEP) in the mesophyll cells to make a 4-carbon acid which is immediately converted to malic acid. The malic acid is then passed across to the bundle sheath cells where it is broken down again to pyruvic acid and CO2. The acid is passed back to the mesophyll cells to be used again, while the CO2 is fed into the reductive pentose-phosphate cycle (Calvin cycle) and converted into sugar and starch.

Identifier Name Description
GO:0015979 photosynthesis The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds.
GO:0005975 carbohydrate metabolic process The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
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:0009058 biosynthetic process The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
GO:0044237 cellular metabolic process The chemical reactions and pathways by which individual cells transform chemical substances.
GO:0071704 organic substance metabolic process The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon.
GO:0015977 carbon fixation A metabolic process in which carbon (usually derived from carbon dioxide) is incorporated into organic compounds (usually carbohydrates).
GO:0019685 photosynthesis, dark reaction A complex cycle of enzyme-mediated reactions which catalyzes the reduction of carbon dioxide to sugar. As well as carbon dioxide the cycle requires reducing power in the form of reduced nicotinamide adenine dinucleotide phosphate (NADP) and chemical energy in the form of adenosine triphosphate (ATP). The reduced NADP (NADPH) and ATP are produced by the 'light' reactions.
GO:0044238 primary metabolic process The chemical reactions and pathways involving those compounds which are formed as a part of the normal anabolic and catabolic processes. These processes take place in most, if not all, cells of the organism.
GO:0016051 carbohydrate biosynthetic process The chemical reactions and pathways resulting in the formation of carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y.
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: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:0044723 single-organism carbohydrate metabolic process The chemical reactions and pathways involving carbohydrates, occurring within a single organism.
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:0044711 single-organism biosynthetic process A biosynthetic process - chemical reactions and pathways resulting in the formation of substances - involving a single organism.
GO:1901576 organic substance biosynthetic process The chemical reactions and pathways resulting in the formation of an organic substance, any molecular entity containing carbon.
GO:0044707 single-multicellular organism process A biological process occurring within a single, multicellular organism.
GO:0032501 multicellular organismal process Any biological process, occurring at the level of a multicellular organism, pertinent to its function.
GO:0044236 multicellular organismal metabolic process The chemical reactions and pathways in a single multicellular organism that occur at the tissue, organ, or organismal level. These processes, unlike cellular metabolism, can include transport of substances between cells when that transport is required.
GO:0009760 C4 photosynthesis The combination of atmospheric CO2 with a 3-carbon molecule phosphoenol pyruvate (PEP) in the mesophyll cells to make a 4-carbon acid which is immediately converted to malic acid. The malic acid is then passed across to the bundle sheath cells where it is broken down again to pyruvic acid and CO2. The acid is passed back to the mesophyll cells to be used again, while the CO2 is fed into the reductive pentose-phosphate cycle (Calvin cycle) and converted into sugar and starch.
