C4 carbon fixation

... For other meanings of C4 , see C4 (disambiguation) C 4 carbon fixation is a common metabolic pathway found in land plants ( C4 plants ). They ... limitation. The C 4 cycle allows for a spacial separation of carbon fixation from respiration, thus allowing C 4 plants to increase concentration of ...

Metabolism

... reaction (dark reaction) Calvin cycle Carbon fixation Drug metabolism Drug metabolism pathways, the ... , important for excretion of nitrogen as urea. Biological nitrogen fixation Nitrogen assimilation Nitrification Denitrification ...

Bacterium

... Some bacteria are able to use molecular nitrogen as their source of nitrogen, converting it to nitrogenous compounds, a process known as nitrogen fixation . Many other bacteria are found as symbionts in humans and other organisms. For example, their presence in the large intestine can help prevent ...

Calvin cycle

... energy carriers to convert carbon dioxide into organic compounds that can be used by the organism. This set of reactions is also called carbon fixation . The key enzyme of the cycle is called RubisCO . The total sum of reactions in the Calvin cycle is the following: 6 CO 2 + 12 NADPH + 12 H ...

Evolutionary developmental biology

... where does it come from? Novelty may arise through several methods including gene duplication and gene regulation. Gene duplication allows fixation of a particular cellular or biochemical function at one locus , leaving the duplicated locus free to fulfill a new function. In contrast, ...

Genetic drift

... alleles usually have a finite lifetime. As the frequency of an allele drifts up and down over successive generations, eventually it drifts till fixation - that is, it either reaches a frequency of zero, and disappears from the population, or it reaches a frequency of 1 and becomes the only allele in ...
