The primary importance of oxygen is that it is critical for cellular respiration in all aerobic organisms. Oxygen also has medical uses including oxygen therapy, high-pressure treatment, and in protective suits made for ...
Oxygen is found throughout the universe. It is formed in the nuclear reactions that take place in stars. Much of the universe's oxygen is contained in water.
Oxygen is required by all living things for respiration. It's also used in industries, water treatment, burning fuels and even protecting humans from harmful UV light thanks to the ozone layer.
Earth's magnetic field is important for sustaining life as it deflects radiation. In addition, it prevents solar winds from the sun blowing directly into Earth's atmosphere.
Plant cells, like animal or other eukaryotic cells, break down food molecules using oxygen respiration in mitochondria. The plants start with simple sugars, which are broken down via glycolysis, then bound to oxygen to p...
The reduction of oxygen to form water occurs during the electron transport system of cellular respiration. Cellular respiration that requires oxygen is called aerobic respiration. It is the mechanism by which glucose is ...
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis...
