Role of energy in the body There are six main forms of energy- Chemicals Heat Electrical Light Nuclear Sound Energy can be measured or expressed by joules or unites of hear (kilocalorie). 1 kilocalorie= 4.184 kilojoules. Sources of energy- Protein 1g= 4 kcal Carbohydrate 1g= 4 kcal Fats 1g= 9 kcal In our bodies we need energy we need energy for everything we do‚ move our muscles‚ talk etc. Without energy we wouldn’t be able to do anything‚ energy is needed for our bodies to function

What is "energy"? Where does it come from? And how do we pay for it? When you learn the answers to these questions‚ you can also learn how to live more efficiently in your home. In this article‚ we ’ll discuss how to be smart about how you use energy‚ how to know when to turn electrical power on and off‚ and how to use natural gas‚ propane‚ and fuel oil in the most effective way. Basic Concepts of Energy Efficiency You can make a lot of progress toward improving the energy efficiency in your

Geothermal Energy Introduction: 1. Good morning every one. My name is…. A. First‚ I have a question for you guys. How many kinds of energy you know until now? (Watch for feedback) B. Ok‚ so have you heard geothermal energy before? Good‚ I am goanna show you some pictures first. C. When I heard this term‚ there are few questions came out in my mind‚ what is the geothermal energy? how the new energy works? Is the

Energy content is an important property of food. The energy your body needs for running‚ talking‚ and thinking comes from the food you eat. Energy content is the amount of heat produced by the burning of 1 gram of a substance‚ and is measured in joules per gram (J/g). Usually‚ fat-rich foods like peanuts and cashews provide more energy than just carbohydrates like marshmallows. You can determine the energy content by burning a portion of food and capturing the heat released to a known mass of

Conservation of energy and transformation of energy. By Paige‚ Stacie‚ Amelia. Objectives Learning about Conservation of energy Learning about transformation of energy Conservation – Preserving a substance. Metabolism Metabolism is a process in which you break down foods into calories and these are combined with oxygen to release the energy that your body needs in order to function/live. This is a very complicated bio-chemical process. Metabolism is essential for the energy for these functions:

Talking Energy Meter The purpose of this project is to build a KWH (Kilo Watt Hour) meter that can alert the users with voice messages. An Energy meter or KWH meter is a device that measures the amount of electrical energy supplied to or produced by a residence‚ business or machine. Electricity is a clean‚ convenient way to deliver energy. The electricity meter is how electricity providers measure billable services. The most common type of meter measures kilowatt-hours. When used in electricity

1) Discuss the three energy systems that are responsible for the production of ATP. Adenosine triphosphate (ATP) is the immediately usable form of chemical energy use for muscular activity. It is stored in most cells‚ especially muscle cells. Other forms of chemical energy‚ such as that available from foods we eat must be transforming into ATP before they can be utilized by muscle cells . Human body cells generated ATP by three methods which are: I. ATP-PC system II. Glycolytic system

"Electrical Energy Consumption" Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable‚ considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal‚ and the use of nuclear power plants. Simply stated‚ the more electricity used‚

Panels- They make electricity so you don’t have to buy it. You don’t have to use coal/oil/something else to create electricity‚ so it saves fossil fuels also. Tankless Hot Water Heater- Heating water is the 2nd highest energy use in the home. This device saves energy by eliminating the storage tank for hot water that has to be constantly heated. You only heat the water you use. Florescent Light Bulbs- These use less electricity than an incandescent bulb for the same amount of light.
