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.

renewable energy? Well‚ because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their‚ unlike coal that once its gone‚ its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun. (Energy Informative) Geothermal is the most cost effective way to get energy‚ with

Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface‚ and even farther down to the extremely hot molten rock called magma. These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

Renewable Energy The use of renewable energy is probably one of the very few solutions for the energy needs of the future. It is considered as a form of safe‚ clean‚ and non terminating energy. In addition to all of that‚ renewable energy always brings marvelous economic benefits to any industry that uses it. Although renewable energy is expensive‚ time consuming‚ and less reliable sometimes‚ yet it still stands out as the solution for the energy needs of the future with respect to a safer environment

GEOTHERMAL ENERGY Geothermal energy is one of energy source types. Geothermal is energy that is gotten from deep of the earth and close parts of the magma with hotwater and its vapour. It is claimed that is useful and practically energy. Geothermal energy sources are argued that is better than other types in variety topics. Despite the fact that geothermal energy have various advantages ; cost‚ location problems and safety should be considerably reasons which are not geothermal energy prefferring

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process that breaks down food to use as energy. The three main stages are glycolysis‚ citric acid cycle‚ and electron transport (Simon‚ Reece‚ & Dickey‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis‚ a team

CONSERVATION OF ENERGY OBJECTIVE The purpose of this experiment is to calculate the gravitational potential energy through experimental values‚ to calculate the theoretical potential energy given the experimental kinetic energy in an isolated system while also using the kinetic energy to find the spring constant‚ and to compare kinetic energies and potential energies in an isolated system to see if they are equivalent. METHOD To calculate the gravitational potential energy through experimental
