krebs cycle summary

Kreb's Cycle - The oxidation of pyruvic acid into CO 2 and water is called Krebs cycle. This cycle is also citric acid cycle because the cycle begins with the formation of citric acid. Citric acid is a carboxylic acid containing ..

It takes place in the mitochondria. The pyruvic acid formed during glycolysis is oxidised 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 the oxidati..

Nitrogen Cycle - Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms cannot pickup elemental gaseous..

The biotic and abiotic components form an interacting system called 'ecosystem'. Producers, consumers and decomposers are the various trophic levels, which are linked by their food relationship forming a 'food chain'. Several food chains are interrelated and interconnected to form a network called ..

The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like change in rainf..

Growth is one of the most fundamental characteristics of living organisms. It is accompanied by differentiation. The growth cycle of an annual monocarpic angiosperm begins with the zygote which undergoes a period of dormancy. Later, the dormant embryo develops into a seedling which ..

All vibrating and oscillating bodies are described by the length of time required for one complete cycle. Time period (T) is the reciprocal of frequency (f). Vibrations and oscillations are also characterised by terms like amplitude of vibrations which is actually the maximum distance..

According to the modified cell principle, new cells arise only from pre-existing cells. Cells transfer their genetic information only by way of cell division. The mode of cell division is largely the same in all living organisms indicating the unity of life. Cell division becomes necessa..
