INTRODUCTION Energy is the basic necessity for life. But for energy no form of life would have ever emerged. We all know energy for providing us light and comfort. It can help us to cool down during summers and feel warm during winters. It also helps us to go from one place to another. All automobiles need energy to run; but even otherwise all other means of transport need energy. But even though we use it every moment of our life and learn about it at school it often remains a riddle

Energy transfers which take place in living organisms The nucleotide ATP (adenosine triphosphate) maintains both catabolic and anabolic reactions. Catabolic reactions e.g. respiration are where larger molecules are broken down into smaller ones with energy being released‚ and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions.

Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

During exercise the body uses up large amounts of energy in three different ways. The ATP/CP system‚ anaerobic system and the Aerobic system all combine during periods of exercise to allow our bodies to continue exercise or playing sport. Most sports have a major system which takes up the bulk of the energy production during the activity and the timing in switching from one to another. This plays a major role in success in the playing arena. In a sport such as Australian Rules football it is important

Aside from our water and food resources needs‚ energy can be considered as one of the world’s most important recourses. Our world has been supplied with two types of energy‚ the Renewable energy and Conventional energy. From the past decades‚ energy has been a huge help on the economic growth. Through the distribution of energy to the world it has been providing much efficient growth on discovering new technologies and giving job opportunities that drastically helped our local and global economy
