Your body is an amazing feat of construction.Ten trillion living cells all working together to make you. All the instructions required to build the You that You became are encoded in your DNA. Forty-Six chromosomes containing more than 25,000 genes have all the instructions required to build a human. Except…Nothing in your DNA explains how to make fuel for the engines that run inside you. Imagine if we had 1000 car manufacturers making millions of cars but no gasoline refineries. A car without fuel is just… art.
The fuel you need is call Adenosine Triphosphate (ATP). For your cells to move, grow, repair, and reproduce they need ATP. To make your muscles move you need ATP, but your DNA doesn’t have any instructions for making ATP.
