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.
Fossil fuels contain carbon that was laid down millions of years ago. Burning it now, as we do in industry, transport and to generate electricity, means that extra carbon is b â¦ eing added to the atmosphere. The natural carbon cycle cannot remove all this extra greenhouse gas and this is causing global warming.
