2 Adenosine triphosphate (ATP) is considered by _____to be the energy currency of life. It is the high-energy ______ that stores the energy we need to do just about everything we do. It is present in the ______ and nucleoplasm of every cell, and all the physiological mechanisms that require ______ obtain it directly from the stored ATP.

3 To break a protein down into its amino ______ you will need enzymes. Enzymes are biological ________ (proteins) that act as _______ and help complex reactions occur everywhere in life.
