All Cells Need Energy Cells need energy to do a variety  of work: Making new molecules. Building membranes and  organelles. Moving molecules in and out of  the cell. Movement.

Where Does A Cell Get  Energy?  Food is broken down to a form  the cell can use. Extra energy is stored in an ATP  molecule, a nucleotide.

How Does ATP Work? Energy is stored in the bond between  the second and third phosphate group. When the bond is broken, energy is  released and ADP is formed.  Adenine Ribose

ATP – Energy Currency Within a cell, formation of ATP  from ADP and phosphate occurs  over and over, storing energy  each time. As the cell uses energy, ATP  breaks down repeatedly to  release energy and form ADP  and phosphate.
