What Does Oxygen Means

The song “Ooh Child” by Five Stairsteps is a song of comfort and hope. It resembles any person going through a rough patch and continuing to have hope their days will become a little easier. They continue to drudge on even though what they are going through in the moment seems unbearable. In time, it will all get a little simpler.

Oxygen is one of the reactants necessary for respiration therefore it is essential for all living organisms. Oxygen is produced through the process of photosynthesis where energy from the sun is converted into chemical energy in the form of glucose.

a. P) Carbon monoxide molecules happen to be just the right size and shape, and happen to have just the right chemical properties, to fit neatly into cavities within hemoglobin molecules in blood that are normally reserved for oxygen molecules.

The graph identifies that at greater pressure the solubility of oxygen is increased. This is shown as 4 atm (yellow) is more soluble at a temperature than 2 atm (red).

Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water. Water composed of two negatively charged oxygen atoms and one positively charged hydrogen. When the temperature is cooler these particles encompass less energy and there is less change that they get separated from each other. In contrast atomic particles are more energetic when the temperature is warmer ands so they will get separated from the hydrogen atom. So cold water holds more oxygen (Mallya 2007). Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water.

Heamoglobin is responsible for transporting oxygen around the body. The intake and release of oxygen molecules is regulated by several factors both external (chemical) and internal to the heamoglobin molecule. The main regulators of hemoglobin's oxygen affinity is oxygen presence. Heamoglobin has a higher oxygen affinity in the lungs and this affinity increases excessively with the amount of molecules it has bound to it (Sears,1999). So, after one molecule of oxygen is bound by the oxyheamoglobin its oxygen affinity will increase until the heamoglobin is completely saturated. Deoxyheamoglobin has a lower oxygen affinity and will disproportionately decrease with oxygen molecules already bound to it. In effect, the reaming oxygen's affinity

The product of the reaction is oxygen (O) and water (H2O).

Smoking in homes where oxygen is used is not allowed. Candles, matches, wood stoves and even sparkling toys should not be used, as they may be sources of ignition. Oxygen cylinders should be kept at least five feet from a source of heat, open flames, or electrical devices. Because body oil, hand lotion and items containing oil and grease can light easily, they should be kept away where the oxygen is in use. Nor should aerosols contain combustible materials near oxygen3

Finally, the oxygen system, known as the oxidative or aerobic system. It is the system that provide benefits to heart and lungs. The oxygen system rather similar to the lactic acid system in that it cannot be used directly as a main source during exercise but it can produce the ATP in large quantities from the other energy sources throughout the body (Williams, et al., 2013).

Often times we think that all life requires oxygen. However, there are many bacteria (called anaerobic bacteria) which do not need oxygen at all! They live down in the soil, under oceans and lakes, and in other areas. To many of them, oxygen is a poison! Yet they are definitely alive. So clearly whether or not something needs oxygen does not show if it is alive. Consciousness as we think of it is probably not a good determinant for life either. It is highly unlikely that bacteria, fungi, plants, and other organisms think, since they lack a brain or nerves. Yet they are definitely alive. Therefore, whether or not something thinks does not show that if is alive. This is the same for movement, because not all living things move-- in fact, many

Oxygen in the air is breathed in through your mouth or nostrils and the air travels into the larynx, then through the trachea, which carries the air to the left and right bronchus, the air then goes down your bronchi. The bronchi become smaller the closer they get to the lungs and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli this is where gas exchange occurs between the alveoli and the blood stream. The oxygen goes into the blood and flows to the left side of the heart, where the oxygen in the blood it is pumped out by the aorta to the limbs. The oxygen stays in the blood by hemoglobin in your red blood cells, the red blood cells only make up 46% of all cells and they release oxygen into the

percent by weight of the oceans and, as a constituent of most rocks and minerals,

“Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive non metal and oxidizing agent that readily forms oxides with most elements as well as other compounds.”By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to found dioxygen, a colorless and odorless diatomic gas with the formula O2. This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth 's atmosphere. Additionally, as oxides the element also makes up almost half of the Earth 's crust.Oxygen is necessary to sustain most terrestrial life. Oxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Conversely, oxygen is continuously replenished by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O

Water has a simple molecular structure which consists of one oxygen atom (O) and two hydrogen (H) atoms. As both oxygen and hydrogen have little to no difference in electronegativity and are non-metals they covalently bond by sharing a pair of electrons to complete their outer shell. When the atoms are covalently bonded they form water H2O. As shown in the diagram 1, after sharing two of its valance electrons, oxygen is left with two pairs of electrons available for bonding.

This review paper is based on research and learned techniques through this semester (Fall 2015), conducted under Dr. Kenneth Kambis in the Adair Hall Facility. Although final approval was authorized in December, there were previous volunteers that were informed under another approval given. In the research project titled: “Individual Variability Upon Acute Exposure to a Normobaric Hypoxic Environment Simulating a Physiologic Altitude Equivalent to 3,500 Meters” it covered and explores hypoxia levels in various ethnic backgrounds at rigorous activity. The concept of metabolism and vasoactivity in certain species systems is highly regulated under laboratory conditions with proper materials, methods, and equipment. Measuring ranging levels of oxygen whether in humans, sheep, rats or mice is essential to understand chemical regulation in the organism’s system. This may be done in vivo or in vitro. In the laboratory, a normobaric hypoxia chamber is utilized to decrease the oxygen content of the chamber atmosphere to a percentage that closely reflects the partial pressure of oxygen in a given hypobaric environment without reducing the atmospheric pressure (Kambis, 2015). Thus the regulation of oxygen in partial pressures is similar to those found in hypobaric atmospheres of up to extreme altitude.
