ATP is adenosine triphosphate which is a compound cells use to store and release energy. It is made on a nitrogenous base (adenine) a sugar (ribose) and most importantly 3 phosphate What is ATP? groups.</p><p>ADP is like ATP but with only 2 phosphate groups. Thus is stores less energy than ATP. Cells use ADP to make ATP. What is ADP?</p><p>Both store energy like a battery, but ATP is fully charged and ADP Explain how ADP and ATP are each like a battery? is partially charged. ATP has more energy stored in it because it Which one is partially charged and which one is has an additional chemical bond to attach the third phosphate fully charged? Why? group. ATP transfers energy efficiently, just the right amount for the cell to do work. The cell can use and regenerate ATP quickly</p><p>ADP + P  ATP storing energy Why is ATP useful to cells? ATP  ADP + P using/releasing energy</p><p>Pumping Na and K into and out of the cell. (Protein Pumps – Active Transport) Name 3 different ways cells use ATP. Contracting Muscle Moving cilia and flagella Synthesis of proteins Produce Light (Firefly)</p><p>It is more efficient to keep a small amount on hand, and make it </p>
