This happens due to anaerobic respiration of the cells. Cells do anaerobic respiration for want of oxygen. Now‚ I have to clarify whether oxygen has not come to ‘sinu auricular node’ and hence it stopped operating heart or due to non-functioning of lungs oxygen is exhausted in ‘sinu auricular node’. Death

How would you convince a friend that microorganisms are more than just disease causing agents? An entire kingdom of microorganisms was brought into life 3 billion years ago. Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular

due to the energy of the sun. (http://en.wikipedia.org/wiki/Bio_ethanol) In the production of bio ethanol fuel‚ the process of anaerobic respiration is included in the process of fermentation. In this process‚ the glucose (C6H12O6) from the feedstock is broken down into two molecules of pyruvic acid through glycolysis. With the presence of yeast molecules from the yeast (Saccharomyces serevisicie)‚ the pyruvic acid is broken down into Carbon Dioxide (CO2) and Acetaldehyde. The acetaldehyde then acts

should be able to carry on a short conversation while doing aerobic exercise. If you are gasping for air while talking‚ you are probably working anaerobically. Aerobic exercise improves long-term endurance while anaerobic exercise improves short-term endurance. Dance tends to use mostly anaerobic activity during technique classes and exercise. Performing repetitive movements will improve muscular endurance. In some circumstances‚ choreographers include vigorous demands on dancer’s aerobic endurance which

needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved with the respiratory system include the sinuses‚ trachea‚ bronchial tubes‚ diaphragm and capillaries. When we inhale‚ oxygen enters the body through the nose or mouth then passes through the trachea (windpipe)‚ which

binomial name given to yeast‚ which is a fungi used in brewing‚ baking and wine making. In brewing yeast is added to the cooled wort in the fermenting vessel. The yeast is initially exposed to high oxygen levels so they can divide‚ but then conditions become anaerobic and the yeast converts the sugars to ethanol and carbon dioxide. After this the yeast is filtered out leaving beer‚ but the yeast can be reused to inoculate the next batch or sold for products such as Marmite‚ yeast extract. Cheese is another
