The tail of an ATP molecule is made up by 3 phosphate groups link together by the help of 2 high energy phospho anhydride bonds.

Explanation:

ATP or adenosine tri phosphate is an energy rich compound that contain adenine base, ribose sugar and 3 phosphate groups.

                  These 3 phosphate groups makes up the tail of ATP molecule.The 3 phosphate groups are designated as alpha phosphate,beta phosphate and gamma phosphate starting from the C5 atom of ribose sugar.

          When ATP undergo hydrolysis the terminal phosphate group or the gamma phosphate group is cleaved from the ATP molecule resulting in the formation of ADP and inorganic phosphate along with the generation of high amount of free energy that is utilized by the cell to perform various cellular and physiological activities.

vitfil [10]
<span>If jogging you should start off with a brisk walk and transition after about 1 minute to a slow jog. Then pick up your pace as your legs become warm with increased blood flow. If biking you should do a few static calf and thigh stretches but don't extend too far as muscles are cold. Then start off your cycling at a very slow comfortable pace. After about a minute you can start to slowly increase your pace until you reach your goal.</span>
