SC.912.L.18.10 ATP

You need to understand how ATP is connected with energy transfers within the cell.

One of the most important compounds that cells use to store and release energy is adenosine triphosphate (ATP).


ATP consists of adenine, a 5-carbon sugar called ribose, and three

phosphate groups.

All cells need energy to carry out their life processes. For example, cells use energy to make new molecules such as enzymes and other proteins. Cells also use energy to build and repair organelles and cell membranes. When energy is needed somewhere in the cell, the chemical energy stored in glucose is released by the mitochondria during cellular respiration and used to produce adenosine triphosphate or ATP. Energy is transferred from glucose to ATP. Then the ATP delivers the energy to the places in the cell that need it.
To release the store energy, bonds between the phosphates in ATP must be broken. To break the bond a molecule of water is added.
