    Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic

    Oxygen      Oxygen, symbol O, colorless, odorless, tasteless, slightly magnetic gaseous element. On earth, oxygen is more abundant than any other element. Oxygen was discovered in 1774 by the British chemist Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion.      Large amounts of oxygen are

  • The Element Oxygen

    The Element Oxygen has a chemical symbol O and atomic number 8. Oxygen was produced by numerous chemists prior to discovery in 1774, but each chemist failed to record it as an element. The main people are British clergyman Joseph Priestley, Swedish pharmacist Carl Wilhelm Scheele and French chemist Antoine Laurent Lavoisier all independently discovered oxygen. But Priestley usually gets the credit for the discovery. The name oxygen was first used by Lavoisier in 1777. Oxygen plays an essential

  • The Function Of Haemoglobin And Oxygen

    935 Words  | 4 Pages

    haemoglobin is to transport oxygen (O2) from the lungs. The haemoglobin and oxygen combination is called oxyhaemoglobin, Haemoglobin that has released oxygen is called reduced haemoglobin or deoxyhaemoglobin which has a high affinity for co2 (Marieb, 2014).for this reason oxygen is bind to the oxyhaemoglobin in the lungs and carried through the blood stream to the tissues. Oxygen is then released to myoglobin (a red protein containing haem that carries and stores oxygen in muscle cells) which is further

  • Zebrafish Oxygen Consumption

    297 Words  | 2 Pages

    When placed in a larger flask, the Danio rerio will consume more oxygen and increase their metabolic rate, because the more they are able to actively swim around, the more water will be continuously pumping into its mouth and across their gills. In the experiment, the amount of oxygen consumption was measured over a 30 minute time period by a Logger Pro instrument. Four different flask sizes were used to change the environment of each zebrafish. By manipulating the size of flask, the experiment was

    Metallobiomolecules METALLOBIOMOLECULES CONTENTS 1. Introduction Metallobiomolecules 2. Classification Metallobiomolecules 2.1. Transport and of to Storage Proteins 2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this, new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

  • Arterial Oxygen Saturation

    pressure of oxygen (Hall Table 44-1). That same table demonstrates that the partial pressures of both oxygen and carbon dioxide in the alveoli decrease as well. However, the alveolar water vapor pressure remains unchanged—constant at 47mmHg no matter the altitude (Hall 561). The most deleterious result of these factors is that less oxygen is being delivered to the tissues. Fortunately for me, Guyton and Hall says that altitude has a relatively insignificant effect on arterial oxygen saturation at

  • Metallurgy: Oxygen and Ore

    1632 Words  | 7 Pages

    Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found, only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena, PbS, etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore, • Isolation of the

    Smithsonian Laboratory Early Atmosphere 1. How abundant was oxygen in the early atmosphere? The earth’s early atmosphere contained only small amounts of free oxygen, produced by the reaction of water vapor with sunlight. The oxygen rich atmosphere that developed later and on which oxygen breathing life now depends was result of the origin and spread of organisms capable of photosynthesis. 2. What evidence do scientists have that the oxygen content of our atmosphere has increased since the earth’s

  • Oxygen During Exercises

    339 Words  | 2 Pages

    muscles begin to work harder during the exercise they will need more oxygen, and glucose and nutrients in order to give the muscles energy as they work harder. This also means that they produce more carbon dioxide as they use up the oxygen so the heart must also pump the blood to the lungs faster in order to get the carbon dioxide out of the body and to exchange it for more oxygen. You could test this by testing how much oxygen and carbon dioxide someone breaths when they rest and when they exercise
