biochemical cycles of carbon

pH plays a very significant role in biochemical reactions. For example, the blood in our bodies is buffered at a pH value of 7.36-7.42 due to bicarbonate - carbonic acid buffer. A mere change of 0.2 pH units can cause death. Certain enzymes get activated only at certain definit..

Carbon Cycle - The cyclic changes that carbon undergoes in nature is referred to as the Carbon cycle. Carbon in the form of carbon dioxide gets added to the air and gets removed from the air constantly. This addition and subtract..

Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmospher..

Any chemical reaction requires a certain amount of energy to get initiated. This is called activation energy. Most of the molecules in a substrate have average kinetic energy, some have high energy and some have low energy. Under normal conditions of temperature only molecules with higher energy re..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rock..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source of oxygen for aquatic organisms. Oxygen in the..

It takes place in the mitochondria. The pyruvic acid formed during glycolysis is oxidized and forms carbon dioxide and water. This reaction also releases molecules called the coenzymes - NADH 2 and FADH 2 . The hydrogen atoms associated with these are the hydrogen atoms released during ..

Biogeochemical Cycles - Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. These nutri..
