Nitrous oxide inside the cells, by a process catalyzed by the enzyme nitrous oxide reductase. Nitrous oxide has significant global warming potential as a greenhouse gas. On a per-molecule basis, considered over a 100-year-period, nitrous oxide has 298 times the atmospheric heat-trapping ability of carbon dioxide (), however, because of its low concentration (less than 1/1000 of that of ), its contribution to the greenhouse effect is less than one-third that of carbon dioxide, and also less than water vapour and methane. On the other hand, since 38% or more of the entering the atmosphere is the result of human activity, and
Nitrous oxide system, and this may be related to its analgesic and anxiolytic properties. Nitrous oxide is 30-40 times more soluble than nitrogen. The effects of inhaling sub-anaesthetic doses of Nitrous Oxide have been known to vary, based on several factors, including settings and individual differences, however, from his discussion, Jay (2008) suggests that it has been reliably known to induce the following states and sensations: A minority of users also will present with uncontrolled vocalisations and muscular spasms. These effects generally disappear minutes after removal of the nitrous oxide source. In rats, stimulates the mesolimbic reward pathway via inducing dopamine release
