| nicotinic |
Nicotinic Receptors form ion channels present in the plasma membrane of cells. Their opening is gated by the neurotransmitter acetylcholine (acetylcholine receptors), and by nicotine. Nicotinic acetylcholine receptors are present in many tissues in the body. The neuronal receptors are found in the central nervous system and the peripheral nervous system. ...

| night sight |
Night vision is seeing in the dark. There are two ways to accomplish this; biologically, and through technology. Technological night vision works on one of two principles. The first is by detecting infrared radiation, which is a form of energy emitted by all objects regardless of the ambient light conditions. A device based on this principle is called an infrared camera. The second is by intensifying the small amount of light present even at night, from the stars and the moon. ...

| nitrogen narcosis |
Nitrogen narcosis or inert gas narcosis is a reversible alteration in consciousness producing a state similar to alcohol intoxication in SCUBA divers at depths beyond 30m. Jacques Cousteau famously described it as the "rapture of the deep". Its precise mechanism is not well understood, but it appears to be a direct effect of high nitrogen pressure on nerve transmission. ...

| nitrogenase |
Nitrogenase (EC 1.18.6.1)is the enzyme used by organisms to fix atmospheric nitrogen gas (N2). Dinitrogen is relatively inert due to its triple bond. The enzyme therefore requires uses a lot of chemical energy in the form of ATP and reducing agents, such as NADH. The product of the reaction is ammonia, which is normally incorporated into glutamate to form glutamine. The enzyme is composed of a dimer of "MoFe" associated with a dimers of "Fe" each. ...
