Unlock the Power of ATP

ATP is Adenosine Triphosphate, a molecule that powers all life on Earth. It is required for essential activities such as pumping ions across membranes and separating DNA strands.

The ATP molecule is made up of three main structures: an adenine nuclear base, a ribose sugar, and 3 phosphates.

Energy is released from ATP when the bond holding the end phosphate group is broken, converting ATP to ADP through a hydrolysis reaction.
