Energy is needed by the body to stay alive‚ grow‚ keep warm and move around. Energy is provided by food and drink. It comes from the fat‚ carbohydrate‚ protein and alcohol the diet contains. Energy requirements vary from one individual to the next‚ depending on factors such as age‚ sex‚ body composition and physical activity level. Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest)‚ the thermic effect of food (TEF‚ the energy required

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

INTRODUCTION Most high-precision machines are positioning stages with Multiple degrees of freedom(DOF)‚ which often consist of cascaded long-and short-stroke linear actuators that are supported by mechanical or air bearings. Usually‚ the long stroke actuator has micrometer accuracy‚ while the Submicron accuracy is achieved by the short-stroke actuator. To build a high-precision machine‚ as much disturbances as possible should be eliminated. Common sources of disturbances are vibrations‚

Abstract Energy in today’s modern society has indeed fluctuated. Energy and its needs of today vary from natural gas‚ to solar to fuel cells‚ and all alternate renewable sources in between. It is an important part of our daily lives from building potential energy as we sleep‚ to when we use kinetic energy to wake –up and get out of bed in the morning in order to grab that first cup of coffee or tea‚ or baking cookies‚ as well as participating on a sports team. We use all aspect of energy to function

Nour Aljafari @55471 WRI 102‚ 11 am Nuclear energy: the future power supplier Ever since humanity has existed‚ there has been an increasing demand for energy as a means of survival‚ from its usage for cooking and warmth‚ all the way to electricity generation for production and agricultural activities. Today‚ over 80% of energy consumption comes from fossil fuels‚ which include coal‚ oil and natural gas (Irvine‚ 2011). However‚ those fuels are not renewable and won’t last for more than a

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

is believed that all three energy systems are used: aerobic‚ ATP-PC and lactic acid. Here is the data that each system contributes to performance in soccer: • ATP-PC= 60% • Lactic Acid= 20% • Aerobic= 20% (Mathews 1974) Centre backs are required to have the following components of fitness: Component of fitness Definition Example Cardiovascular endurance “body’s ability to continue exertion while getting energy from the aerobic system used to supply the body with energy” (Lemouse 2014) Being able

ENERGY Energy is a physical quantity that describes the amount of work that can be done by a force.FORMS OF ENERGY ENERGY CRISIS……..? An energy crisis is any great shortfall 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

Alternative Energy for Future Nowadays the most common energy resources come from Fossil Fuel‚ which according to research it shows that more of 85% of all energy that is consumed in the United States. It takes millions of years for the Fossil Fuel to actually develop and ready to be used‚ and the main concern of Fossil Fuel is that it cannot be consumed over and over again or reused. Through this analysis it can be assumed that because it takes millions of years for the fossil fuel to develop‚
