“The energy for life comes from the sun.” Outline the role of the photosynthesis process to explain what is meant by this statement. (3 marks) chlorophyll 6CO2(g) + 6H2O(l) + energy C6 H12 O6 (aq) + 6O2(g) 2830 kJ glucose Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose‚ sucrose‚ starch and cellulose. Carbohydrates are high energy compounds

behind Energy Drinks 1. When we say that something gives us "energy”‚ what does that mean? What is a biological definition of energy? When we say that something gives us “energy” it means we can get sugars or carbohydrates and lipids from that. Humans need to eat carbohydrates and lipids to provide fuel for our body’s metabolism. Human body must have these chemicals in order to function and different food sources provide different types of energy. The biological definition of energy is the

Sustainable energy is defined as the provision of energy that meets the needs of the present without compromising the ability of the future generations to meet their needs. Sustainable energy sources include all renewable energy sources‚ such as tidal power‚ wind energy‚ wave power‚ geothermal energy‚ hydroelectricity‚ solar energy‚ and bioenergy. The world is in need of more sustainable energy. New technologies are being developed and expanding on to aid in preserving the earth and going green

find new energy sources. Because present energy sources are running down. So‚ alternative energy is so popular in these days. Because it has no danger to human life like nuclear powerplants‚ it is free to use and it has no waste. There are three types of alternative energy sources: Solar‚ wind and water. This report will be about solar energy. Its purpose is giving some information about solar energy to mechanical engineering students and engineers and calling attention on solar energy. The

Renewable Energy Is Capable of Meeting Our Energy Needs Despite having public support and advantages over other energy sources‚ renewable technologies have been repeatedly characterized as unable to meet our energy needs. People have been presented only a choice between conventional fossil fuels and nuclear power. This‚ however‚ is a false choice. Renewable energy can reliably generate as much energy as conventional fuels‚ and can do so without producing carbon emissions or radioactive waste

ENERGY CRISIS INTRODUCTION 1. An energy crisis is any great shortfall (or price rise) in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. The crisis often has effects on the rest of the economy‚ with many recessions being caused by an energy crisis in some form. In particular‚ the production costs of electricity rise‚ which raises manufacturing costs. For the consumer‚ the price of gasoline (petrol)

Functional Energy: Fatty Acids (Fats) vs. Amino Acids (Proteins) Fats‚ proteins‚ and carbohydrates are sources of energy for the body. Although carbohydrates are the largest source of energy‚ fats and proteins‚ however are just important‚ they contain essential amino chains not found in carbohydrates and are critical to Adenosine Triphosphate (ATP) manufacturing on a cellular level. ATP takes the chemical energy from the food to the mitochondria to transform it into energy for the cells. (Dictionary
