cell. Cellular respiration involves a series of enzyme-mediated reactions. The equation below shows the complete oxidation of glucose. Oxygen is required for this energy-releasing process to occur. C6H12O6 + 6O2 -> 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized PURPOSE

presence of suspended solids in water which reduces penetration of light‚ resulting in a decrease concentration of oxygen. Acidity is the concentration of hydrogen ions in the water body. A pH of 5.5-7.5 (meaning slightly basic water) is preferred in water supplies. Dissolved oxygen is the measure of oxygen dissolved in aqueous solution whilst biochemical oxygen demand is the measure of oxygen used by organisms. Both of these are monitored to prevent harm caused to bacteria and organisms. Natural Factors

is from paleocimatologists look at bubbles of air trapped in the ice‚ which contain samples of the atmosphere from that time period. Paleocimatologists observe the oxygen in the ice\water molecules. Most of the oxygen atoms are in two forms called isotopes the two different isotopes are 18o and 16o which stand for 18-oxygen and 16-oxygen. The proportions of these two are really similar but different 18o is slightly heavier than 16o. The proportions of these two isotopes depend on the average temperatures

blood being pumped around the entire body for survival. The respiratory system also has importance in the body as it is the system to transport air into the lungs to aid the diffusion of oxygen to the blood.The primary functions of the cardiovascular and respiratory systems is to provide the body with nutrients and oxygen and get rid of waste products such as carbon dioxide. During short term exercise stimulus there is a significant change in heart rate‚ blood pressure and respiratory rate as it adapts

C1 Revision Notes Atmosphere is a mixture of gases that surrounds the Earth. The three main chemical components present in air are Nitrogen‚ Oxygen and Carbon Dioxide. Trace amounts means only a very tiny concentration of gas is present. An element is made up of 1 type of atom. A compound is made up of 2 or more types of atom that are chemically bonded. A mixture also contains more than 2 or more type of atoms but they cannot be chemically bonded. A pollutant is a waste matter that contaminates

they have to face is receiving oxygen‚ which for most organisms is mostly important to their lives. The intertidal organisms use gills‚ and these gills also have the chance of drying out from the hot sun. These organisms also discovered a way to protect themselves from drying their gills‚ what they do is close off themselves and keep their neutral activities to a minimum level until the tide returns. Some other organisms have a type of lung that lets them get oxygen when they are out of the water

actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides add the colours. An oxidizing agent producing the oxygen required to burn the mixture. An agent e.g. Sulphur‚ that burn the oxygen and produce hot gases. Binders are required to hold the mixture in a lump. The ability of producing coloured light from the principles of fireworks have allowed this technology to be used for both industrial and
