Oxygen toxicity

plants, animals and all living things is released back into the atmosphere during the process of respiration. Energy is required for all living things to carry out life processes therefore stored glucose must be converted to energy by respiration. Oxygen is used to break down carbon stored as sugar for energy by the process of respiration. Carbon dioxide is released as a waste product back into the atmosphere C6H12O6 + 6O2 → 6CO2 + 6H2O. With the combined effect of photosynthesis and…

Periodontiits: Periodontal disease is one of the most prevalent disease throughout the world (Albandar 2011). It is a chronic bacterial inflammatory infection leading to destruction of supporting tissues of teeth (Moffatt, Whitmore et al. 2011). It is second to dental caries as a cause of tooth loss among adults in developed countries (Gautam, Jindal et al. 2011), affecting 47.2% adults aged 30 years and older in the US (Eke, Dye et al. 2012). Organisms causing periodontal diseases: In a…

only do the high temperatures cause heat damage to the delicate lining of the dog 's nose and upper airway, the toxic chemicals in smoke cause tissue injury. The carbon monoxide in the smoke binds to the red blood cells in the dog 's body, preventing oxygen from being carried and causing tissue death. Additionally, the potentially harmful substances that are burned in the fire can irritate the airway and bind to the air sacs in the lungs, hindering breathing. Recognizing the signs of smoke…

takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the…

Marcel Duchamp | Fountain “All in all, the creative act is not performed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualification ..” Do you know, which artist could have said this? That was a citation of Marcel Duchamp, one of the most important artists of the 20th century. In the next few minutes I will give you some informations about the person, who said this quite interesting words. Duchamp‘s life…

acid esters. (Gunawardena, 2009) Esters have closely identical functional groups with carboxylic acids which include an acyl group bonded to an oxygen which is bonded to another molecule the only difference is that carboxylic acids are bonded to hydrogen atoms (acyl group bonded to an –OH) while esters are bonded to an alkyl group(acyl bonded to a oxygen bonded to an alkyl group). (Refer to figures 1&2 for comparison) Fig. 1 structure of a carboxylic acid ester Fig. 2 structure of a…

The aquatic animal known as the crawfish has become well-known in the scientific community due to its common use in a lab or the natural field. While some of its species are known for their invasiveness and “affect [on the] fundamental aspects of aquatic systems like water quality” (Pearl), the crawfish has provided insight into various fields of science because of its ability to be easily manipulated. This small animal has been utilized by many researchers studying the origins of the animal’s…

Is there any chance global warming, dramatic effects are changing the earth’s atmosphere slowly or rapidly? The industrial revolution begun in the mid- 17th century, it was a transition from agriculture era to manufacturing production era. This was the time where technology was improving and aspect of our daily life was changing. The first powered gasoline car (Benz Patent-Motorwagen) was made in 1807 and made by Karl Benz. Gasoline is made from fossil fuels, which is released into the…

The pH of something can be determined by using the specific pH scale. The scale is based off of numbers ranging from 0 to 14. The lower the number is the more acidic something will be and the higher the number is the more basic something will be. It is important to note that 7 act as the neutral number, where neither it is considered acidic of basic (5). It is found that rain water that is unpolluted is coincides with carbon dioxide and has a pH of 5.6. Often, the pH around the world of…

Cellular Respiration takes place on the level of the cell, inside the mitochondria. This is the process of breaking down food in the presence of oxygen to form ATP. ATP stands for Adenosine Triphosphate which is an energy bearing molecule found in all living cells1. Things such as bacteria can perform this with their outer membranes. When a person runs, they use cellular respiration to create energy in the form of ATP which allows their muscles to move. Many other energy-consuming reactions of…
