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.

Writing Practice Renewable energy has a positive effect on economy. Do you agree? As the fossil fuels resources have been continually mind in recent years. The lack of energy resources is one of the greatest challenges faced by government in Australia. Therefore‚ the new energy resources are promoted and developed such as nuclear power and renewable energy. Some in Australia argued that development of new energy resources not only alleviates the shortage of fossil fuels resources and protects

Nowadays‚ some people who supported renewable energy have many questions for fully relying on renewable energy in the future. A factor why people do not consider renewable energy is economics. However‚ the fact is that renewable energy can solve many economic problems. Anna Leidreiter expresses that the benefits of traditional energy are shared in only a few stakeholders; renewable energy is owned by popular‚ so the big business do not agree renewable energy.

and businesses‚ geothermal power plants use superheated fluids from the earth’s geothermal energy to generate electricity. When magma heats up the water from underground‚ it creates superheated fluids. When these super-heated fluids reach the surface they will be turned into steam. This steam will then power a turbine‚ which will in turn power a conductor. The conductor will then produce electrical energy. ¬¬¬¬¬¬To create enough steam to power the steam turbines‚ the superheated fluid must
