    the most serious problems faced by the Earth is the depletion of ozone layer. It is also one of the reasons that cause global warming. The ozone is a colourless gas that found in the stratosphere of the upper atmosphere. The ozone layer is about 17-25 kilometers above the Earth. The layer of ozone gas is a layer which protects us from the ultraviolet radiations which is harmful from the sun. The ozone layer contains high concentrations of ozone molecules (O3) that absorb ultraviolet (UV) radiation

    The consequences of ozone depletion are very severe. Prolonged exposure to ultraviolet radiation can lead to higher risks of skin cancer such as melanoma. Ultraviolet radiation causes mutations that can lead to skin cancer. Squamous cell carcinoma is also a common cancer that caused by exposure to ultraviolet rays. Prolonged exposure to ultraviolet radiation can also lead to higher risks of cataract and cause sunburn. Furthermore, prolonged exposure to ultraviolet radiation can lead to higher risks

    THE CAUSE OF OZONE DEPLETION In this topic, only the anthropogenic causes of the ozone depletion will be discussed. Ozone-depleting substances (ODS) generally contain chlorine, bromine, fluorine, carbon, and hydrogen in varying sizes and are frequently depicted by the general term halocarbons. Chlorofluorocarbons, carbon tetrachloride, and methyl chloroform are important human-produced ozone-depleting gases that have been used in many applications including refrigeration, cleaning of electronic

    OZONE LAYER DEPLETION The ozone layer or ozone layer is a region of Earth 's stratosphere that absorbs most of the sun’s ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth 's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly

    Ozone depletion is a man made phenomena which industries release CFC (chlorofluorocarbons), rising up to the upper atmosphere exposing to high energy UV radiation from the Sun. Even though that CFC has low reactivity, flammability and toxicity, it remains inert in the troposphere as they disseminate among the stratosphere whereas the UV rays strikes the CFCs molecules and releases chlorine. The chemical reacts with ozone (O3/oxygen), a natural combination of O2 (oxygen) molecules and free oxygen

    REGULATION OF FATTY ACID METABOLISM Introduction: Fatty acids are produced by acetyl-CoA by its transformation to malonyl-COA by various known as fatty acid synthases and this takes place in cytoplasm.Acetyl-COA is fuether transformed into various fats molecules taken from carbohydrates through a process known as glycolytic pathway.This pathway basically requires glycerol along with three fatty acid molecules to form a structure called as neutral fats or triglycerols.Two fatty acid molecules basically

  • Citric Acid Cycle Research Paper

    1083 Words  | 5 Pages

    The Citric Acid Cycle/ Kerbs Cycle/ TCA The Citric acid cycle is important as anaerobic glycolysis can only harvest a fraction of the energy from glucose. In the citric acid cycle there is aerobic respiration of pyruvate from step ten in glycolysis to C02 and H2O. This oxidation of pyruvate can greater a higher yield of ATP. The citric acid cycle occurs in the mitochondria where ten ATP is produced. The main purpose of the citric acid cycle is to harvest electrons from the citric acid cycle and

    Introduction Ozone is the form of oxygen consisting of three atoms of oxygen instead of two. It is considered an air pollutant when it is found at ground levels and it is a major component of smog.1 It is formed by the reaction of various air pollutants when in the presence of sunlight.1 Ozone is used commercially as a bleaching agent and is also used to purify water supplies.1 On the other hand, ozone is toxic and is a gas which is harmful to any person's health when generated near the earth’s

    divided into several layer called ozone. Ozone is a molecule of three oxygen atom bound together and it is unstable and highly reactive molecule. Ozone is naturally in stratosphere when highly energetic solar radiation strikes oxygen molecule (O2) and cause the two oxygen atom to split apart in a process called Photolysis. A freed atom collide with another oxygen then it join up forming ozone, O3 . The formation of ozone is explained with certain mechanism where both ozone molecule,O3 and oxygen molecules

    Advantages of Vitamin E Oil on Your Skin Exposure to ultraviolet rays from the sun is among the primary factors leading to significant destruction to your skin cells. After the penetration of the rays into your skin, they first destroy the oxygen molecules available in your skin cells. In return, the oxygen molecules get changed to free radicals. Although oxygen is a crucial part for the occurrence of life, free radicals from oxygen are not only poisonous in nature but also highly reactive
