GO Term : GO:0045729 respiratory burst at fertilization GO

Namespace  biological_process Obsolete  false
description  The phase of elevated metabolic activity, during which oxygen consumption increases, that occurs at fertilization. An enhanced uptake of oxygen leads to the production of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals. Capacitation, a necessary prerequisite event to successful fertilization, can be induced by reactive oxygen species in vitro; hydrogen peroxide is used as an extracellular oxidant to cross-link the protective surface envelopes.

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:0019953 sexual reproduction A reproduction process that creates a new organism by combining the genetic material of two organisms. It occurs both in eukaryotes and prokaryotes: in multicellular eukaryotic organisms, an individual is created anew; in prokaryotes, the initial cell has additional or transformed genetic material. In a process called genetic recombination, genetic material (DNA) originating from two different individuals (parents) join up so that homologous sequences are aligned with each other, and this is followed by exchange of genetic information. After the new recombinant chromosome is formed, it is passed on to progeny.
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:0000003 reproduction The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
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:0051704 multi-organism process A biological process which involves another organism of the same or different species.
GO:0022414 reproductive process A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
GO:0044703 multi-organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving another organism.
GO:0044702 single organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving a single organism.
GO:0009566 fertilization The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).
GO:0007338 single fertilization The union of male and female gametes to form a zygote.
GO:0045730 respiratory burst A phase of elevated metabolic activity, during which oxygen consumption increases; this leads to the production, by an NADH dependent system, of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals.
GO:0045729 respiratory burst at fertilization The phase of elevated metabolic activity, during which oxygen consumption increases, that occurs at fertilization. An enhanced uptake of oxygen leads to the production of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals. Capacitation, a necessary prerequisite event to successful fertilization, can be induced by reactive oxygen species in vitro; hydrogen peroxide is used as an extracellular oxidant to cross-link the protective surface envelopes.
