are the carbon cycle and oxygen cycle

Oxygen Cycle - 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 th..

Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmosphere. Because of the position of its electrons, an atom of carbon can form covalent bonds with hydrogen, oxygen, nitrogen, phosphorus and other carbon a..

The C 3 type of carbon reactions occurs in the strome of the chloroplast. It is also called Calvin cycle after its discoverer, Melvin Calvin. a) In the first step CO 2 is accepted by a 5- carbon molecule, ribulose -1,5 biphosphate (RuBP) and 2 mo..

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 subtraction is so well balanced that the pe..

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 at..

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 nutrients are called 'macro nutrients' ..

Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitrogen. Thus the process of converting atmospheric n..
