The cell membrane and the associated transport proteins found in the membrane are responsible for regulating the movement of hundreds, if not thousands, of different types of molecules into and out of the cell.
Among the gases emitted when fossil fuels are burned, one of the most significant is carbon dioxide, a gas that traps heat in the earth's atmosphere. Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere.
Burning fossil fuels puts carbon into the atmosphere. Other smaller sources include industrial processes such as cement manufacture and natural gas flaring.Fossil fuels provide most of the energy that supports human transportation, electricity production, heating and cooling of buildings, and industrial activity.Oil used to be the dominant fossil fuel, but as of 2008, coal is dominant (40% to oilâs 37%).he Future of Fossil Fuels. The future of anthropogenic fossil fuel use depends on human decisions about energy use at the international scale. If we collectively choose to depend more and more on fossil fuels, our emissions will increase.
