The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes  the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.he image below shows where you might encounter each portion of the EM spectrum in your day-to-day life. The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom).
ATP is a high energy compound made up of one adenosine molecule attached to 3 phosphate molecules, the molecules are then bound together by the high energy bonds. There are only a few steps in the ATP-PC which is why it provides energy so quickly, they are: (courtesy of http://www.ptdirect ...ow does the ATP-PC system work? The ATP-PC system is the most important out of all the 3 energy systems, it provides you with the most power because it produces ATP more quickly than any of the other 3 systems and because of this it is essential in sporting exercises like 20m, 40m and 100m sprint activities.
ATP adenosine triphosphate is the energy molicule that makes the muscle contract when it is present. 1  Comments. 2  Report.
