Professional sport competitions are highly competitive. Athletes sometimes search for advanced technology and medicine for performance enhancing solutions.

The protein, creatine, is a highly controversial supplement available to athletes wanting to increase performance. Creatine is a natural substance produced in the body. It is taken up by muscle cells and converted to phosphocreatine.

Phosphocreatine is a source for the production of adenosine triphosphate, ATP.

Why would having more ATP be advantageous to an athlete?

Do you think professional athletes should be banned from the use of creatine supplement? Why or why not?

Adenosine triphosphate (ATP) is involved in the energy production in among others muscle cells. If more ATP is available a muscle cell can then mobilize more energy for muscle work. A(n) (professional) athlete is of course interested in having more energy available for work. If more creatine is available it is easier for the muscle cells to produce more ATP so more energy would/could be available. So the interest of athletes in this substance is understandable. If it should be allowed or not is a somewhat controversial and difficult question. On one hand: ...
