What is the gas that is produced in the burning of fossil fuel?

What is the gas that is produced in the burning of fossil fuel, that can help regulate the blood pressure in the human body and acts as a neurotransmitter?

 

Any idea?

 

Thanks....

Gass produced during combustion of fossil fuels

  • sulfur dioxide (SO2),
  • sulfur trioxide(SO3),
  • nitric oxide (NO),
  • nitrous dioxide (NO2).
  • Carbon dioxide (CO2)
  • Water vapour (H2O)
  • Carbon monooxide (CO)
  • Methane (CH4)

 

Nitrogen oxides are formed due to combustion of nitrogen molecules in the fuel and also because of nitrogen compounds present around the engine, environment consist of about 80% nitrogen.

Nitrogen oxide has a major importance in cell signaling in mammals it act as a vasodilator but only at moderate concentration in the blood, above threshold concentration it causes inflamation and also can be carcinogenic.

Neurotransmitters chemicals which are endogenous that helps in transmiting signals from a neuron to a target cell. Nitrogen oxide play a role of Neurotransmitter in mammals. 

Vasodilation is dilatation of blood vessels refer to widening of blood vessels which help in easy blood flow, which decreases blood pressure. Nitrogen Oxide play a role of Vasodilation but only at moderate concentration thus helps in decreasing the blood pressure.

When fossil fuels are combusted, carbon dioxide is produced, which is a contributor to global warming. Nitrogen oxides and sulfur oxides are also produced. Nitric oxide or NO, is a gas that causes vasodilation. This lowers blood pressure when it causes the smooth muscles in the artery walls to relax. It also helps to maintain homeostasis when the kidneys are able to regulate fluid in the body, which in turn affects blood pressure. In terms of the nervous system, nitric oxide serves as a neurotransmitter between the neurons of the nervous sytem. It acts on not only neurons in a pathway from the presynapse to the postsynapse, but can also diffuse to nearby neurons causing information to be transmitted. It is an important compound used in cell signaling.

The combustion of fossil fuels include carbon dioxide gas and water vapor as the main products. They also include sulfur dioxide (SO2), sulfur trioxide(SO3), nitric oxide (NO), and nitrous dioxide (NO2). The sulfur impurities are caused by combustion of the impurity hydrogen sulfide, mercaptans, or other sulfur compounds in the original fossil fuel. The nitrogen oxides are caused by combustion of nitrogen molecules in the fuel.

Nitric Oxide is a neurotransmitter and has been associated with neuronal activity. Nitric Oxide is an important regulator and mediator of various process in the nervous system. These include vascular smooth muscle relaxation, resulting in arterial vasodilation and increasing blood flow.Nitric oxide is also used as a vasodilation in blood vessels.
